Input: Question: What was the highest chart position of the song in which Jenner's voice can be heard at the start? Passage:Pink Floyd, then an unknown band, began to receive paid bookings including at the Marquee Club in March 1966 where they were watched by Jenner. The band played mostly rhythm and blues songs, but Jenner was impressed with the strange acoustic effects that Barrett and Wright created during their performance. Jenner traced Waters and Mason to their flat, and with his business partner and friend Andrew King was subsequently invited to become their manager. Although the pair had little experience of the music industry, they shared an appreciation of music, as well as a childhood history. Using inherited money they set up Blackhill Enterprises and purchased new instruments for the band, as well as equipment which included a Selmer PA system. Under their guidance, Pink Floyd began performing on London's underground music scene, notably at a venue booked by the London Free School in Notting Hill, as well as the notorious "Games For May" concert at London's Queen Elizabeth Hall on 12 May 1967, an event set up by both Jenner and King. Jenner and King's diverse array of social connections were meritorious, gaining the band important coverage in The Financial Times and The Sunday Times. Jenner's voice can be heard at the start of Pink Floyd's 1967 "Astronomy Domine", the opening track on the album The Piper at the Gates of Dawn (UK edition).
