I didn't know that KISS's version was a cover. If I didn't hate kiss enough- I hate them more now.
Yeah that really shocked me too. But I only found that out when I was doing sound for The Zombies (Argent is the keyboard player in them) and they played it. It was bloody fantastic too.
Kiss have never done a song called God gave rock and roll to you. They did one called God gave rock and roll too you 2. It pretty much the same tune but the lyrics are different. Its more of a sequel than a cover. No mention of snails or Cliff Richard in the kiss song, sadly. Personally I like the Kiss song, mainly because of its association with Bill and Ted's Bogus Journey. Which is one of the best films ever made.
