During 1973 the group issued a single, "Early Morning", which had been co-written by Birtles with Goble and Johnson. It peaked at No. 56 on the Australian Kent Music Report Singles Chart. In January 1974 Mississippi appeared at the Sunbury Pop Festival and then released another single, "Will I?", which was co-written by Birtles and former bandmate, Cotton. It reached No. 26. They toured the United Kingdom from May that year, where they "made little headway" and various members left the group. In London they met with fellow Australian musicians Glenn Shorrock (ex-Twilights) and Wheatley – both expressed a desire to return to Australia and work on a new version of Mississippi.
