Thanks for tipping this one Stuart. At the risk of upsetting Ringo fans there can't be many groups under the general umbrella of 'rock music' who can match 10cc for all 4 players being proficient vocalists.
Yeah, this is a very enjoyable collection. I’m listening to it as I write this. Full of pop ideas well performed and with a great 1968/69 vibe.
It brings to mind the slightly weirder, but still creative and poppy in parts album by Ramases called “Space Hymns” on Vertigo. This sounds a couple of years earlier, but “Space Hymns” had 10cc guys making the music, and that album would be s nice follow-up listen to this CD.
