I have played guitar with an all girl band enfemme at their request because their regular guitar player could not make the 2 shows.
I learned their original songs on the set list and knew the cover songs they had on there as well.
So tell me why a band comprised of crossdressers has to do songs dealing with crossdressers?
A band tailors what songs they play to fit the crowd at the venue,if the bar owner wants a cover band do covers if he is OK with originals then do those.
To be honest there are no rules and how is a song any different because of the gender of the one playing it?
