yes, meself
there was a bit[ i think] about the village band falling asleep during a sermon, and the leader of the band waking up and playing devil among the tailors, the village band members also played m,usic for the church service.
back to the c sharp d box, i imagine you would have g and d basses for playing in g major, but am not absolutely sure about that.
    to deal with scotch bonnet.
tony hall also uses right hand harmony, and your suggestion that basses are just for percussion is idiotic. here is your quote
Irish semitone players heve to search for them & most don't bother- any use of 'irrelevant' basses you've come across just illustrates the Irish view that the bass buttons are superfluous to Irish music, but may have a value as percussion.
tell that to jackie daly , the c sharp d is quite capable of basses in d major possibly to some extent g major.
then we have the d d sharp, it must be possible to play in d major using it like a one row using basses. if wanted
if there is someone that knows this defintely rather than chancers like scotch bonnet, i do not mind being corrected about the d dsharp.
Two semitone systems that are not as limted as scotch bonnet makes out HERE IS SOMEONE PLAYING A D DSHARPwith lots of basses
