What was Elton mania like when he was really big in the early to mid 1970's?

I used to sit in my brother's ute and listen to Yellow Brick Road on his 8-Track cette - I was probably 13 or 14 yrs of age. Elton is certainly a very talented musician. I used to listen to T-Rex, Creedence Clearwater Revival and a couple of others I can't remember. Oh yeah, Bread.
