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 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.
After years of unsuccessful singles, they were signed to Mickie Most's Rak label, and had three Top 20 successes in 1973 with "Crazy" (No. 12), "Hypnosis" (No. 16) and "Dyna-mite" (No. 4).
At the peak of their career, they also enjoyed British number one singles with "Tiger Feet"; and "Lonely This Christmas" (1974), an affectionate Elvis Presley pastiche; plus "Oh Boy" (1975), a cover of the Buddy Holly hit, which also featured on their album Mud Rock Volume 2. "Tiger Feet" sold over 500,000 copies in the UK and a million copies globally.
Like contemporaries Sweet, their most successful period came when their records were written and produced by Nicky Chinn and Mike Chapman: in 1975 they had seven singles in the UK Top 40 totalling over 45 weeks on the chart, the most by any artist in 1975. "Oh Boy" was the only number one single produced by Chinn and Chapman that they did not also write.
"Lonely This Christmas" gets seasonal airplay on British radio and television, (along with Slade's "Merry Xmas Everybody" and Wizzard's "I Wish It Could Be Christmas Everyday"). The band also embraced the burgeoning disco craze, as exemplified on their 1976 single "Shake It Down" which reached No. 12 in the UK chart. After "Tiger Feet" they released "The Cat Crept In" which reached No. 2 in April 1974, which was written to exploit Les Gray's vocal impression of Presley. Their next single "Rocket" reached No. 6 in the UK, after which they released another track from their album Mud Rock, a cover of "In the Mood". This was released under the name of "Dum" ("Mud" spelt backwards), but it failed to chart.
After the success with "Lonely This Christmas", they cracked the Valentine's Day market with "The Secrets That You Keep", which reached No. 3 in February 1975. Around this time Mud wound up their contract with Rak releasing three further singles, "Oh Boy" (their third and final UK No. 1), "Moonshine Sally" (No. 10) and "One Night" (No. 32). Mud also split from Chinn and Chapman in mid-1975 and signed to Private Stock (licensed to Philips in Continental Europe). There they enjoyed three more British Top 20 hits within seven months: "L'L'Lucy" (No. 10), the ballad "Show Me You're a Woman" (No. 8) and the disco-influenced track "Shake It Down" (No. 12). The latter two singles saw them gradually moving away from glam rock, which was now unfashionable. Keyboardist Andy Ball, formerly of Candlewick Green, joined the band briefly during this period, to be replaced in early 1978 by Brian Tatum.
