Not technically a miss-heard lyric, just an accidental cock-up...
Once, when UE were rehearsing Live On, I totally accidentally sang "there's more things in the world/Than holding hands & sniffing girls".
The whole band completely lost it & we couldn't finish the song all nite!
Back in the day (we were teenagers when Different Class came out)
A lass asked me, "Why is he singing, 'we want cheese scones, we want cheese scones?'"
