The Yardbirds played in the afternoon at the Fillmore, San Francisco and it was an amazing show. Jeff Beck and I got a lift from the venue with some guys and one of them had recorded it.

It was a pleasant surprise to hear it played back en route from the gig. The recording quality was poor from the small dictaphone type recorder, but the playing of the band was great.

I guess this tape just disappeared into the ether.
