thanks dr wu for your swift answer, but you can see my problem, surely the two of the greatest talents ever must have been in the same group at the same time time.
somebody told me "blind faith" but can't find any evidence..
I know Clapton & Beck played together in the studio, as I've got a compilation album with a track called Tribute to Elmore. Clapton's playing lead, & Beck is playing bass.
As for Blind faith, that was Clapton,Baker,Winwood & Grech.
The Virgin encyclopedia of rock says that EC was replaced by Beck (1965) and Samwell-smith was replaced by Jimmy Page, Beck left during a US tour. So in answer to your question; Not in the yardbirds. Incidentally Jimmy Page did alot of session work, playing base as well as lead.
Clapton and Page played 2 songs together at the 1983 MS benefit at the Royal Albert Hall. This was organised by Ronnie Lane.
The songs were "Tulsa time" & "Layla".
