A mutual acquaintance on Facebook posted a memory of playing in a band who once accompanied a singer who also hosted a game show. His wife was the sister of songwriter and Capitol Records co-founder Johnny Mercer, and the charts he gave to the band were apparently written by Mercer himself.
Anyone able to identify who this could have been? I did find an obit for Mercer's sister, but no husband was mentioned, and no other info on whether he had any other siblings.
