I have no idea what the state of Paul's record sales are these days. I suspect they are way down from his early solo days.
Anyway, I wonder what prompts Paul to go back into the studio. Setting "Kisses On The Bottom" aside, is it just a desire to record or is it based solely on when he feels he's compiled enough good songs for an album?
Anyway, my idea is this: Macca should record Lennon-McCartney songs primarily associated with John, with totally different arrangements and maybe a twist or two on vocal interpretation. First of all, he wouldn't need to write any new songs. Secondly, he'd still get a cut of the songwriting royalties. But most importantly, it might be fascinating to see what he could do with some Lennon songs. What do you think? My choices would include: "Not A Second Time", "Anytime At All", "No Reply", "I'm A Loser", "Come Together", "Yer Blues", "Across The Universe", "Help", "You Can't Do That", "This Boy", "Rain", and just for fun, "Bad To Me".
I realize some John fans might find this idea appalling, but it could be kinda cool.
