Seeking Ten Years After song


Anyone know the name of the song where Alvin Lee detunes his lower E string and goes into a savage one-string solo?

I saw him do it live and pretty sure it was on an album.

Wasn't it to symbolize 10 years after the start of rock and roll? Or perhaps the Buddy Holly et. al. crash?
The Elvis theory doesn't really hold water as his first record was 12 years before, in 1954. Besides, why would Ten Years After relate to Elvis the Pelvis?
