Jack Collier And His Charley Boppers

According to Stephen McParland, "All American Boys: The Walker Brothers Genesis", 2002, page 10, "Jack Collier & His Charley Boppers" were fronted by Ernie Freeman and fellow L.A. session musicians, many who were later to be associated with Phil Spector's "Wrecking Crew", including Rene Hall (guitar), Irving Ashby (guitar), Earl Palmer (drums), Plas Johnson (sax) He quotes "Freeman used the recording alias of "Jack Collier" because he was under contract with Imperial Records as a recording artist".
