By 1973, the band had a six-song demo tape ready for mailing, and Scholz and his wife Cindy sent copies to every record company they could find. The songs on the demo were "More Than a Feeling", "Peace of Mind", "Rock & Roll Band", "Something About You", "Hitch a Ride" (under a different title) and "Don't Be Afraid" (which would be eventually released on "Don't Look Back"). The group received rejection slips from several labels—RCA, Capitol, Atlantic and Elektra among the most notable—and Epic Records rejected the tape flatly with a "very insulting letter" signed by company head Lennie Petze that opined the band "offered nothing new". The tape that received the most attention contained embryonic renditions of future songs that would appear on Boston's debut album. Financial reality encroached the dream for Delp, who departed shortly thereafter because "there just wasn't any money coming in". By 1975, Tom Scholz was finished with the club scene, concentrating exclusively on the demo tapes he recorded at home in his basement. Scholz was renting the house and spent much of his funds on recording equipment; at one point, he spent the money he had saved for a down payment on a future home on a Scully 8-track. He called Delp to provide vocals, remarking, "If you can't really afford to join the band or if you don't want to join the band, maybe you'd just want to come down to the studio and sing on some of these tapes for me." Scholz had given the Mother's Milk demo to a Polaroid co-worker whose cousin worked at ABC Records (who had signed one of Scholz's favorite bands, the James Gang). The employee forgot to mail the tape out and it sat in his desk for months until Columbia began contacting Scholz, after which he sent the tape to ABC.
