@slaw, yeah that Lennon album is a real glimpse into his Rock ’n’ Roll heart. It was originally marketed and sold as one of those "As Seen On TV!", real cheesy kind of things (the cover was a garish yellow). There is another guy whose roots are just about identical with John’s (Chuck Berry, Brill Building songwriting, Everly Brothers harmonies)---Dave Edmunds. Dave didn’t record his first solo album (he had already made a couple of albums as the leader of Love Sculpture) until the final year of The Beatles, so he hit the ground running, fully formed and developed. His 1st (Rockpile---album title, not the group he later had with Nick Lowe), 2nd (Subtle As A Flying Mallet), and 3rd (Get It) albums are absolute Rock ’n’ Roll masterpieces. If you don’t already have them, do yourself a huge favour and get them!
