Motherfunk

Appropriately, I went for a drink with a couple of the other mummies from our group, and the band playing is called Motherfunk. The singer in the sparkly dress (although not obviously singing!) is Susie's, one of the aforesaid mummies, sister.
They were very good. You'll be asking why I've come home so soon, but I've still got a sore frote. I didn't ask if the rest of them normally dress like that...
