Sorry Bob, I should have A/Bed them before.
Yes the Bionic is a re-recording with full group and a similar but different lead to the Psyche version. Psyche is much better, longer, cleaner and much better constructed as a song, they messed up the breaks and chorus/verse structure on the re-release. I can see vocal group fans preferring it though, just for the fact of the group. It took some analysing though, just listening to You Tube versions wouldn't really tell you either way.
The disco version is OK, I'm not into it, you might dig it Ian, it takes a while for the chorus to come in and it's cute when it does. I can picture you in the gold lamE suit dancing to this one.
I'd not describe the New Image Psyche 45 as psychedelic at all, its soul of its era (mid 70s?) with a slightly electric funk influence. OK of its kind but not for me.
Thanks for all the input Bob and the rest of ya.
