I used to think that Boney M were really cool, being a geek I was inspired by space travel, physics and so on. Nightflight to Venus appealed for obvious reasons, although I thought the button on your backside was a bit naughty (it's "left side"). I can't remember the other song I really liked but until only a few days ago (I'm 35) I thought they were singing "When we hit those atoms there's going to be a big hello." I didn't know what a big hello was but I figured it was artistic licence for the wacky effects you get in nuclear physics. It's "islands," not "atoms." I'm still gutted....
