By the way do you know a couple of members of Gonzalez played on a couple of tracks on T.Rex's last album Dandy In The Underworld? in case you're interested they were Bud Beadle, Steve Gregory, Colin Jackas and Chris Mercer.
Re: ZebedyZac The two versions are totally different to each other, the superior Sidewalk mix has a much more commercial full on 70s disco sound to it, where the EMI version is far more minimalist in production
At least one website lists this as a US chart single in 1977, but I cannot find any further information to support this. I know it was a UK chart single in 1979, and that's the year on the label, but was it released in 1977, perhaps on a different label?
