Jon Mark is a singer-guitarist who was a member of John Mayall's
blues band in the 1960s. He left with singer, sax-player Johnny
Almond and set up the Mark-Almond band in the early 1970s. Jon has
since made some solo albums. Does anyone know if Jon Mark made any
records with Jimmy Page in the mid-1960s, as I've found a tape of
them performing Dylan's "Don't Think Twice".
