Jenny Wren is the best for me. For everything in it. And, as a reworking of Blackbird, for me, Macca could just go ahead and rework a whole bunch of Beatles melodies of his. That would be so good.
But, has it taken Macca 35 years to realise he could sound like the Beatles again? I don't know his post-Beatles output so well, but IMO, C&C sounds like the stuff he was doing on TWA. I just hope that C&C is a sign of things to come!
