Charles McKenzie, a New England representative for ABC Records, first overheard the tape in a co-worker's office. He called Paul Ahern, an independent record promoter in California, with whom he held a gentleman's agreement that if either heard anything interesting, they would inform the other. Ahern had connections with Petze at Epic and informed him—even though Petze had passed on the original Mother's Milk demos. Epic contacted Scholz and offered a contract that first required the group to perform in a showcase for CBS representatives, as the label felt curious that the "band" was in reality a "mad genius at work in a basement". Masdea had started to lose interest in the project by this time, and Scholz called Goudreau and two other performers who had recorded on the early demos, bass player Fran Sheehan and drummer Dave Currier, to complete the lineup. In November 1975, the group performed for the executives in a Boston warehouse that doubled as Aerosmith's practice facility. Mother's Milk was signed by CBS Records one month later in a contract that required 10 albums over six years. Currier quit before he knew the band passed the audition, and Scholz recruited drummer Sib Hashian in his place. Epic had signed an agreement with NABET, the union representing electrical and broadcast engineers, which specified that any recording done outside of a Columbia-owned studio but within a 250-mile radius of one of those studios required that a paid union engineer be present. As such, the label wanted the band to travel to Los Angeles and re-record their songs with a different producer. Scholz was unhappy with being unable to be in charge, and John Boylan, a friend of a friend of Ahern, came on board the project. Boylan's duty was to "run interference for the label and keep them happy", and he made a crucial suggestion: that the band change their name to Boston.
