A while back the "Message" took on the subject bands with the word "twins" in their name (Thompson Twins, Cocteau Twins) that did not include any actual twins. But what about other band names based on familial relationships? 

In the case of sisters, both The Pointer Sisters and Sister Sledge did feature actual sisters. Not so with The Sisters of Mercy, though. Dee Snider might have looked a little like somebody's sister (if that somebody was Sammy Hagar), but Twisted Sister had no actual sisters. And the name Shakespeare's Sister owed more to The Smiths' song catalog than to any siblings of the Bard of Avon. It's a similar story for the Manchester trio that had a hit in 1986 with "Break Out." What was the full name of the band?
