If we are going to play that game, then Black Sabbath – they have played fairly recently with the original line up.
Erm, they did a press conference as the original line up and promptly fell out with Bill Ward and he didn’t play the shows.
Question on definitions – how are we meant to define “original line up?” – most bands go through changes in the formative period, but often establish a stable line up prior to recording the first album. U2 fall into this category, t’Edge’s brother was originally part of the band, but had left before they recorded, and they’ve kept a stable line up for their entire recording career.
And what about bands that change their names? U2 also fall into this category btw.
