Although an official union contract dates this session as being held on July 21 1955 it is possible that the session could have been before that date.

The Legacy release Elvis 75 - Good Rockin' Tonight lists the date of this session as being July 21 1955, whereas the Sony/BMG release Elvis 75 lists 'Tryin' To Get To You' as being recorded on July 11. Also, Elvis At Sun lists the session date as being July 11 1955

RCA received tapes from Sam Phillips in December 1955, and where no tapes existed they used dubs from SUN singles for their masters (see below).

In March of 2007, Sony decided to go through all of Elvis' masters. They retransferred everything and remastered all tracks including repairing as many clicks, pops, bad edits and dropouts as they could. They have used these newly mastered recordings on their new releases since 2007 including budget soundtracks, Legacy releases, the 30 disc Complete Elvis Presley Masters collection and the Franklin Mint package. These 2007 remasters were not used on FTD's A Boy From Tupelo, the masters were all remastered again from scratch on that set.

There exists a fantastic original 15 ips SUN tape copy for the masters of the fifth and last Sun single 'I Forgot To Remember To Forget' (C&W side) and 'Mystery Train' (R&B side). This tape was handed over by Sam in January 1956 and is therefore referred to as the 16th Sun tape box. The tape was first used for the 50s Box, but has now been retransferred flat by Sony with even better results in spite of the flat, original, unprocessed sound. This is partly due to better NAB calibration.

The new transfer of 'I Forgot To Remember To Forget' has already found its way to two recent releases. First the 2003 upgrade of Great Country Songs and later the same year it was used for Second to None. The introduction of noise-shaping when converting back to 1-bit DSD native after first converting to 8-bit PCM-narrow in the Sonoma environment to allow equalization isn't very impressive on either one of them, especially considering the result was aimed at 16 bit PCM only. However, the slight above 10 kHz raise done by Sony for these two releases isn't considered out of place at all - it's right on target actually. It's just the method that seems a little complicated. The distorted clipping of vocal peaks on Second to None is simply devastating since this source has so much dynamic range. The Great Country Songs version was clipped as well, but not nearly as much. The Elvis At Sun version of 'I Forgot To Remember To Forget' is a slight improvement with total absence of clipping being the only major audible difference compared to Great Country Songs. 

The equally great new Sony transfer of the unprocessed, dynamic 'Mystery Train' makes its debut here on Elvis At Sun. The original, full-ending-to-the last-note version derived from lost Sun Tape Box #1 (that was reported to us by Sven Adamski in 1999) has been recovered from the best available source (tape copy with compression and severe generation loss) and matched with precision during the fade-out, using all the tricks in the book and for once stretching all the Elvis At Sun restoration rules. The result of this impossible task is stunning considering the circumstances. 

According to Sam Phillips 'Tryin' To Get To You' would have been the R&B side of Elvis' sixth Sun single. Unfortunately the surviving RCA copies suffer from more compression than usual and not even this Sony transfer of the recovered RCA 30 ips tape can do anything about that. It is a shame how the compression takes over during the loud vocal parts, but apart from that the new source and version isn't all that bad, at least not compared to what has been released before.
