Mud are an English glam rock band, formed in February 1966. Their earlier success came in a pop and then glam rock style, while later hits were influenced by 1950s rock and roll and rockabilly, and they are best remembered for their hit singles "Dyna-mite", "Tiger Feet", which was the UK's best-selling single of 1974, and "Lonely This Christmas" which reached Christmas number 1 in December 1974. After signing to Rak Records and teaming up with songwriters/producers Nicky Chinn and Mike Chapman, the band had fourteen UK Top 20 hits between 1973 and 1976, including three number ones.
