Tongue-in-cheek title aside, this short-but-sweet compilation makes a convincing case for latter-day Pink Floyd as solid students of rock-pop songcraft. Pink Floyd are not known for making particularly danceable music. This image, designed by Hipgnosis under the pseudonym T.C.P. (Thorgerson, Christopherson and Powell) is perhaps a little play on that, featuring ballroom dancers guyed to the ground so they cannot move.
