Pink Floyd had stabilised with a line-up of Barrett, Waters, Mason and Wright by mid-1965, and after frequent gigging that year became regulars on the underground live circuit in London. While Barrett was the dominant member, writing most material, singing most lead vocals and playing lead guitar, Wright played a supportive role, playing keyboards and singing, with occasional lead, and writing his own material. As the most qualified musician, Wright was responsible for tuning guitars, and would often tune Waters' bass for him in concert. Later on, he had a Strobotuner to tune guitars silently during gigs. In the band's early days, before acquiring a full-time road crew, Wright was responsible for unloading the gear at the end of each gig.
