I used to think that the first lead vocal we hear is Jagger, maybe sped up a little. But that's not him; esp. because we hear Jagger a little bit later. Who is that? And who does the part "..play the Blues, play the Blues everybody. The Rolling Stones are a great f&ckin group ( thats a lotta sh*t) then I heard the group, now I know their a lot of sh*t"
