There's the Rub is the fifth studio album by rock band Wishbone Ash. It is the first album to feature guitarist/vocalist Laurie Wisefield, who would be a major part of the band's creative direction for the next 11 years. The album is considered by many to be a highpoint of the band's recording career. The title is taken from Shakespeare's Hamlet; "To sleep—perchance to dream: ay, there's the rub." The track "F.U.B.B." caused controversy because of the acronym's meaning ("Fucked Up Beyond Belief") upon the album's release. Moreover, the haunting ballad "Persephone" would go on to become one of the band's most popular live songs. The lyrics of "Lady Jay" are based on the Dartmoor folk legend about Kitty Jay.
