No, this is Englishman Steve Miller: a pianist who frequently appears on bluestinged albums from this era.
Led outfit Steve Miller's Delivery. Played the piano with The John Dummer Blues Band (1st album), Free (1st album), Carole Grimes, Hatfield & the North (where Pip Pyle, drummer of Blodwyn Pig and Chicken Shack also has a history), Alexis Korner, Daddy Longlegs, Caravan... Issued albums with Lol Coxhill...
Quote from an interview with Carol Grimes in "Beat Instrumental"
of Febr. '71:
Carol is telling about the period when the group Babylon, which
she was a member of, was falling apart:
"A guy called Steve Miller was running a club called Rambling
Jacks, and he booked us to play a gig there. Well, when he found out the
band had broken up he offered me a place in his band..."
And the article continues: "The original Delivery was formed
many years ago in Cambridge by Pip Pyle (drums), Phil and Steve
Miller (guitar and piano respectively), and Jack Monck (bass).
Alexis Korner was so impressed by the band that he took them on
the road and took Steve to the Essen Pop Festival ('67). For several months
after Essen, Alexis, Steve and Robert Plant played and recorded
together, until Plant left to join Zeppelin. Steve split at the
same time and began a very successful career doing sessions for such people
as Daddy Longlegs, John Dummer and Free (first album), yet
maintaining his regular place in the line-up of Delivery."
