What songs exactly? I can likely find where and when.
The very best started in April of 1953, when Nelson Riddle began arranging (nothing against Alex S or any others, esp B. May), at KHJ on Melrose (the "then Capitol" studios), and especially when he sang on a U47. Of course Frank sounded great on any microphone, C12, several others, but something magic about the combination of 47, Nelson, KHJ, the very best players and songs...and of course, Frank at his peak.
