Often the performer is not the composer.
You may include the performer (version) with the song title.
Please use correct iRp chart-info format.
Example:
Denzil's Best (Tommy Flanagan) - Denzil Best
...title……….....(version) …………….- composer(s)
It’s helpful to include time-sig and rehearsal marks. I added the heavy final-bar and also the END instruction to have the player avoid the turnaround the last repeat, reset default key to match the ending chord as that can be helpful for correct player function.
