There is something in what you say about performing to different audiences and adapting. But my point is that you have to stick to what you do best.
before the lockdown i was singing regularly in two community halls to senior citizens, but because i was in ireland, i could sing trad songs, because the irish are closer to their tradtions.
i did adapt, singing some songs popularised by luke kelly and also the clancy brothers, but i also was able to sing more esoteric material too it was a listening audience and i did not sing pop songs, absoluteley no need to murder buddy holly or englebert humperdinck.
why? sing musack that can be heard in every supermarket and music that is treated as wallpaper music.
I sing because i like the material I sing, I COULD HAVE BEEN A POP SINGER AND EARNED MUCH MORE MONEY. I chose not to.
Folk clubs have become a place where failed popsingers can live out their failed fantasies, it was never thus in 1966 when i first waked in to a folk blues club, neither was it like that at les cousins in soho in 1967, yes it was a broad church, but no body singing Buddy Holly, Or Cliff Richard
