Later in 1966, the Masters Apprentices shared a gig with pop star Bobby Bright of Melbourne duo Bobby & Laurie, who was impressed and recommended them to his label, Astor Records. A few weeks later, they were contacted by Astor, which requested a four-track demo.Keays, p. 41, 45, 50, 52, 54, 55 The band went to a local two-track studio to record it, but realised that they had only three suitable songs to record. Needing a fourth track, guitarists Bower and Morrison wrote a new song, "Undecided", in about 15 minutes; the backing track was cut in about the same time. The title came from the fact that they were undecided about a name for the song when quizzed by the studio owner, Max Pepper. The biting fuzz-tone of Bower's guitar on the track was a fortunate accident; it was caused by a malfunctioning valve in his amplifier, but the group liked the sound and kept the faulty valve in until after the session.
