I'm just beginning to put together a treatment and budget for a documentary series that requires a few sequences of 'Music Hall' talent performing during the early 1910's - 1920's. It's unlikely that enough archive material could be found and so In short I'm looking for Male and Female vocalists familiar with the popular music of that era, choir members, pianist and possibly ouher musicians. As well as an authentic music hall to shoot at. This is all a bit out of my usual speciality, so any advise would be very welcomed.
