Sam Phillips an impromptu session featuring the four musicians. Phillips challenged the four to achieve gold record sales, offering a free Cadillac to the first, which Carl Perkins won. The contest is commemorated in a song by the Drive-By Truckers. By the mid-1960s, Phillips rarely recorded. He built a satellite studio and opened radio stations, but the studio declined, and he sold Sun Records to Shelby Singleton in 1969. In 1977 Sam's sons, Knox and Jerry, were working with John Prine at the Phillips Recording Studio when Sam Phillips joined them to oversee recordings that were eventually included on the album "Pink
Phillips' Sound Recording Services mine [and Harrison] on the other side that's never been released before." Other customers of Phillips' studio included The Swinging Blue Jeans, Brian Epstein, Freddie Starr, Willy Russell, Liverpool F.C. supporters club, and players from Everton F.C.. Denny Seyton and The Sabres recorded "Little Latin Lupe Lu" (Bill Medley) in the studio in 1963. Phillips closed the studio in 1969, the record shop in 1974, and died in 1984, at the Royal Liverpool Hospital. The recording of The Quarrymen acetate and the site of Phillips' Sound Recording Services was commemorated on 26 August 2005, when a Blue Plaque was unveiled
