A tribute act, tribute band, tribute group or tribute artist is a music group, singer, or musician who specifically plays the music of a well-known music act. Tribute acts include individual performers who mimic the songs and style of an artist, such as Elvis impersonators covering the works of Elvis Presley or groups like The Iron Maidens, an all-female band that pays tribute to Iron Maiden. Many tribute bands, in addition to playing the music of an artist or group, also try to emulate the vocal styles and overall appearance of that group, to make as close an approximation as possible. Others introduce a twist on the original act; for example, Dread Zeppelin plays Led Zeppelin songs in a reggae style with a lead singer dressed up as Elvis Presley, while Gabba perform the songs of ABBA in the style of the Ramones. Tribute bands usually name themselves based on the original band's name (sometimes with a pun), or on one of their songs or albums. The first tribute acts to emerge may have been Beatles tribute bands, such as The Buggs, who attempted to look and sound like The Beatles while playing their songs. However, one might argue that Elvis impersonators qualify as well. Neil Innes's band "The Rutles", a humorous take on the Beatles, achieved tremendous success with a film, All You Need Is Cash, backed by George Harrison. Although initially created to honor the original bands, many tribute bands have grown to have their own fan base. Only One Direction have performed to hundreds of thousands of fans, have completed four UK theatre tours, and debuted in their own show on London's West End in October 2015. Those bands and artists that have inspired a cult following in their fans tend to have a significant tribute band presence as well, such as Little River Band, Lynyrd Skynyrd, Black Sabbath, Journey, Genesis, Led Zeppelin, Deep Purple, Styx, Pink Floyd, AC/DC, Iron Maiden, Kiss, Madonna, The Misfits, Queen, Alice in Chains, Grateful Dead, Van Halen, ABBA, The Rolling Stones, The Who, The Cars, R.E.M.
