Spinal Tap are a fictional English heavy metal band created by the American comedians and musicians of The T.V. Show, who wrote and performed original songs as the band: Michael McKean, as the lead singer and guitarist David St. Hubbins; Christopher Guest, as the guitarist Nigel Tufnel; and Harry Shearer, as the bassist Derek Smalls. They are characterized as "one of England's loudest bands".

A metal umlaut is a diacritic that is sometimes used gratuitously or decoratively over letters in the names of mainly hard rock or heavy metal bands—for example, those of Blue Öyster Cult, Queensrÿche, Motörhead, the Accüsed, Mötley Crüe and the parody bands Spın̈al Tap and Green Jellÿ.
