Soon after forming Mudcrutch, with Randall Marsh on drums, the group added a second lead guitarist, Mike Campbell.

Leadon and Campbell shared lead guitar solos during Mudcrutch's live shows in and around Gainesville, and also on their recording of "Up in Mississippi".

Leadon left Mudcrutch in 1972[2] and moved to Los Angeles, following in the footsteps of his older brother Bernie, who had recently formed the Eagles with Randy Meisner, Glenn Frey, and Don Henley.

Recording personnel included original band members: Petty, Leadon, Mike Campbell, and Randall Marsh.

[2] The band went on to continue being intermittently active with touring, and recording a live album and a follow-up to their debut with Mudcrutch 2, in 2016.
