John Williams was the lead vocalist in a band called The Authentics with his brother Berne. They had a residency at the Marquee. London supporting The Yardbirds. Indeed, Berne Williams introduced Jimmy Page to the Yardbirds. They recorded one unreleased single with Page as producer and harmonica and guitar. John Williams then recorded a solo album for Columbia in 1967 which is exceptional and very hard to find these days. He then recorded an album with Jimmy Page and Big Jim Sullivan under the name Maureeny Wishful. Another hard to find record but exceptionally good. John recorded two tracks with Dave King (Spell) at Shield Studios, Kettering in 1968.
