Reception - An instrumental that is suppose to give this album a concept feel. I think the radio sounds and the opera ones are suppusedly heard from Earth, while the rest of the song sounds like a journey to it. But of course, I'm reading too much into it, and let's not forget, this is still McCartney (not saying it as a bad thing). While not long enough to bore you, this is still pretty unnecessary and can be regarded as filler.
Getting Closer - That's more like it. A great catchy rocker with great bass and drums work. I'm not a big fan of Paul singing in that goofy voice accompanied by the silly backing vocals (like at 1:17 - 1:30) but a good performance and song overall. Also, I am too a fan of the chaotic ending.
We're Open Tonight - Great acoustic song. Excellent McCartney vocals wheather he sings, harmnonises or hums. I like the bongos (?) at 0:32 (and 0:54 again) that seem to be passing from the left channel to the right one. Pleaseant tune, but I'd certainly wish they would've made it longer.
Spin It On - An angry, spontaneous song that has always been kind of neutral to me. If there is one thing I like, it's definitely the guitar. The drumming starting at 0:11 is pretty cool, too. McCartney's delivery is definitely suitable for the song's atmosphere. I've never been a big fan, but it's decent enough.
Again and Again and Again - I've always enjoyed this one. For what it is, it works. Love it when McCartney joins Denny. I kind of like the guitar solo and the organ being played in the background. The repeated "again and again and again and again..." at the end gets annoying and I certainly could do without that. Not a very strong song, but for a Denny written and sung song it's better than I first expected.
Old Siam, Sir - Amazing song. The guitar-driven intro is excellent. The keyboards riff is great. The climax at 1:05 may as well be the best moment on the whole album. At 2:15 there's a weird sound going on in the background (mainly in the right channel) which lasts for about 15 seconds until the next climax arrives. Anyone knows what is it? Paul's shouting is very powerful, souding a bit like he did 10 years before in 'Oh! Darling'. It may as well be the best song on the album.
Arrow Through Me - Another great one. Love the synth riff. It does give it a disco feeling, though it's certainly not as disco as 'Goodnight Tonight'. Incredible harmonies at 1:40. What I've always liked about this song is the contrast between the first and the second choruses. On the first one, McCartney sings in a falsetto voice (0:41), while the second time around (1:59) he sounds completely different, almost like his vocie is about to crack at times. Great horn sections and great use of reverb (as Bobber mentioned), giving McCartney's voice a spacey feeling. One of my personal favourites.
Rockestra Theme - I like the idea of doing these kind of unfinished instrumental jams and McCartney seems to be enjoying it very much, weather he does them all by himself (McCartney I and II) or with such big names as here. But sometimes I do wish he'd finish them. I think this would've worked better with a set of lyrics. It's enjoyable, and I love the piano licks, especially at 0:54 and 1:42 (Paul? or maybe John Paul Jones?) and the ending is good (even with Paul's silly vocals), but in my opinion, it could've been better.
After The Ball/Million Miles - A suite of 4 ballads, grouped in 2 songs, starting with this one. It's a pretty emotional ballad, maybe because of Paul's soulful performance. The lyrics are pretty good, too. Weird guitar lick at 1:02, but it works. The song builds itself up slowly, finally descending into a guitar solo which connects it with the next number, 'Million Miles', which sounds just boring and uninspired. It's not extremely bad, it's just not going anywhere. Paul's voice is good, but the accordion ruins the song in my opinion. All in all, the first song is great, the second mediocre at best.
Winter Rose/Love Awake - I'm a big fan of the first song here, so I'll do my best to defend it. First of all, I really enjoy the atmosphere : very mystical. The harmonies starting at 0:09 are heavenly. I wish they'd carry throughout the whole song. Paul's voice does sound a bit hoarse, but I do like it. I don't know, to me, he sounds like a desperate, powerless man hoping for that "winter rose" to bring some light into his life. I am probably reading too much into it, and I don't think McCartney was trying to sound like that, but that's how I've always seen it. At 0:55 the chorus sounds great. The second song is not as good, but still decent enough. It's a nice pop song, with not much else to add.
The Broadcast - Same as 'Reception'.
So Glad To See You Here - The exact kick the album needed after 'The Broadcast'. Awesome rocker. 1:01 not too keen on the backing "Carry on, carry on". The 'We're Open Tonight' reprise is enjoyable enough. Good song, definitely better than 'Rockestra Theme'.
Baby's Request - I've never been a jazz fan, but I think this is a nice, mellow tune. At 1:42 I like the horns. The piano sounds great throughout. Good song and a worthy album closer.
All in all, while not as good as 'Band on the Run' or 'Venus and Mars', I think 'Back to the Egg' is a worthy swan song for Wings.
P.S. I struggled with this review and it didn't turn out to be as inspired as I expected. Anyway, I haven't heard any McCartnney solo stuff that came after this, until 'Chaos and Creation In The Backyard'. So, I'll try to listen and participate on each one of them. Keep it up !
