In early 1967, King attended an old boys' reunion at Charterhouse. He said he went there to show off, "oust Baden Powell as their most famous Old Boy." When they heard he was going to be there, a school band recorded a demo tape for him, and a friend, John Alexander, left the cassette in King's car with a note, "These are Charterhouse boys. Have a listen". Calling themselves Anon, the band consisted at that point of Peter Gabriel, Tony Banks, Anthony Phillips, Chris Stewart and Mike Rutherford, then all aged 15 to 17.
