I wonder if Stew is trying to print accurate swing notation.

BIAB always shows swing as two equal length eighth notes when in fact they are not. The first is twice as long as the second.

Many fake books will show an icon at the beginning of a song saying play tied eighths as a dotted eighth followed by an eighth.

I have never seen any music show triplet (swing) in any way other than tied eighths and often without the explanatory icon.

I have often thought that BIAB should put this on their printed music
