They released a self-titled debut LP in that year which reached No. 21 on the Kent Music Report Albums Chart. "Mississippi" was produced by Jones and Ern Rose via the Bootleg label, which had been set up by Tudor and Brian Cadd. According to Australian musicologist, Ian McFarlane, it "featured a harmony-rich rock sound heavily influenced by Crosby Stills Nash and Young and The Band. One of the highlights was the lush, orchestrated epic 'Save the Land'." In October it provided the single, "Kings of the World" – "Another of the album's standouts" – which reached No. 10 on the "Go-Set" National Top 40. In late 1972, Mississippi were joined by Beeb Birtles (ex-Zoot, Frieze) on guitar and vocals, Colin DeLuca (ex-Fugitives) on bass guitar and Derek Pellicci (ex-Ash) on drums. This line-up released a single, "Mr Moondog", in December and toured Australia. They appeared at the Sunbury Pop Festival in January 1973. During 1973 there were several changes in the line-up, with Johnson replaced, in February, by Kerryn Tolhurst (ex-Country Radio) on guitar and mandolin; he was replaced in turn by Harvey James (ex-Clydehouse, Sayla, Wendy Saddington Band) on guitar, a month later. Another single, "Early Morning", was released in July, which peaked at No. 56 on the Kent Music Report. They supported the Jackson Five on the Australian leg of their tour in October of that year. In that same month DeLuca and Mower left and were replaced by Andre Santos on bass guitar and vocals. Santos was replaced two months later by Charlie Tumahai. In 1974 they appeared at the Sunbury Pop Festival again. Their next single, "Will I?", appeared in May which peaked at No. 31 on the "Go-Set" National Top 40. They toured the United Kingdom in 1974 and broke up. In London Birtles, Goble and Pellici met with former Masters Apprentices bass guitarist, Glenn Wheatley, who agreed to become their manager, should they decide go back to Australia. Wheatley was eager to return to Australia after working in the United States the UK. In the UK, the group met Glenn Shorrock (ex-the Twilights, Axiom) who had been there for four years, and was also returning home.
