In March of 1961, Frank Sinatra attempted double duty, recording with Billy May at the Capitol Tower, then moving down the road a mere 1.7 miles to Radio Recorders to record a second same-day session with former Tommy Dorsey alum Sy Oliver for Reprise, and on 4-track tape for the first time.  This had to be a tiresome and frustrating exercise and, indeed, the sessions at Radio Recorders wound up producing zero material for the new Reprise album, and all the album tracks wound up being re-recorded two months later at the more-familiar confines of United Recorders.  (Whether the double-duty aspect impacted the decision to re-record is, to me at least, unclear.  It may have been strictly a dissatisfaction with the musical arrangements.)

One track, “In the Blue of Evening,” did wind up being released, finally, in 1993, as a bonus track on the second CD issue of I Remember Tommy.  It also appeared in the “suitcase” two years later, and then on the 2001 Reprise compilation, Greatest Love Songs. 

All three versions appear to stem from the one-and-only stereo mix, likely a digital one, and from the same digital source, as they do stay in sync with each other.  Furthermore, the 1993 and 1995 versions appear to be the same mastering, as the waveforms look identical, while the 2001 version is slightly compressed, being roughly 3 dB RMS louder overall than the 1993 and 1995 versions.
