In November 1955, 15 tapes of Sun recordings were turned over to RCA. Producer Steve Sholes made some handwritten notes on them, probably in January 1956. These were analyzed by Lee Cotten in the book 'All Shook Up, Elvis Day-By-Day' (Popular Culture, Ink., 1985). In the second edition (1998), further research gives us more accurate interpretations. Ernst Jørgensen's latest book, 'A Boy From Tupelo' gives us a some new revelations as well.

Eight tapes with Sun recordings were shipped from New York to the vault in Indianapolis to be destroyed in 1957. These were described in the magazine 'Elvis - The Man and His Music' No. 23 as well as a status report on the 15 known tapes. At first it seemed that 10 tapes were sent to Indianapolis, but in the second edition of 'All Shook Up', Lee Cotten identifies three of them as being one, but listed on three rows.

Most of the 15 original tapes are lost today. Some were probably destroyed. Others appear to have been stolen. The Harbor Lights tape was found in Steve Sholes' desk after his retirement. The vocal channel slapback tape containing When It Rains It Pours was lost for years until found inside another tape box in 1982 by coincidence.
