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. Their last single to reach the British charts was a cover of the Bill Withers song "Lean on Me" which reached No. 7 in the UK in December 1976. 1977–1979: downfall to disbanding "Lean on me" was followed by in 1977 Gray's solo version of "Groovy Kind of Love" on Warner Bros., which peaked at No. 32 in the UK. Also in 1977, with Private Stock in financial difficulties, the band moved to RCA. Their first single on RCA was "Slow Talking Boy", a folk rock song composed by John Kongos, and featuring Davis playing a Vox 12-string guitar-mandolin; they performed this song on BBC TV's Top of the Pops, but without reaping any chart success. Mud's next single, "(Just Try) A Little Tenderness", was their final appearance on any major national chart, stalling at No. 98 in Australia. Three more singles, all cover versions, followed in 1978 before RCA dropped the band and Gray quit for a solo career.
