Tull comes close. Anderson at one point said the band was over without barre but he reformed the band this millenia without him so at this point he is the only one who has always been with the band and indeed many people think his name is jethro tull. The band has had a crazy amount of turnover even early in its career and a crazy amount of ex members in other well known bands. Heck in the first or second studio album there is a song about members that left the band before its success. The 20 year album had a little flow chart of band members who ended up in other groups.
