Jackie Lomax:

No blues man, but since
1) I loved Heavy Jelly Mk II, and
2) Eric Clapton is featured on the following single...

"Sour Milk Sea" (George Harrison)/"The Eagle Laughs At You" (Lomax) APPLE # APPLE 3
A-Side: More energy than melody. Fast, snarling guitar (Eric C) and stressed vocals.

B-Side: Riffy but still more melodic. Powerful brass. Better than the A-Side.
