he is a genius, and I think one of the best ever, but let's give Mr Taupin his due as lyricist.....as "solo" artist, I would put him near top along with Bob Dylan and James Taylor...presley was great performer with unbelievable pipes, but he didn't write nor play music.
these guys were amazing songwriters...there harmonies are among the best ever....dont know if they are in R&R hall of fame...travesty if they are not
