The writing process varied from song to song. "Some came from Eric's bass lines," noted Navarro, "some from guitar, some came from Perry, some came from drum riffs, and some just came from free-form jams. There was really no formula." Avery wrote several songs, including "Mountain Song", "Had a Dad", "Jane Says", and "Summertime Rolls" (the latter two of which he also created the guitar parts for). For his songs, Avery came up with lyrical concepts that Perry Farrell would create lyrics for; for example, "Had a Dad" dealt with Avery discovering he had a different biological father.
