Stamp, 70, lost his battle with cancer at Mount Sinai Hospital in New York City the same day Daltrey and Pete Townshend were due to take the stage in Detroit, Michigan for a gig, and to honour his late pal, the rocker took a moment out of his show to celebrate the producer's life.
Crediting Stamp with the group's success, he said, "(Stamp) flew into the universe on a pair of rainbow wings. Chris, we can never thank you enough - well, I can't, for what you brought to my life."
Born in London, Stamp met the band in 1963 while making a film about the growing British rock scene. Three years later he founded the group's Track Records label, which released Jimi Hendrix's hit Purple Haze and Arthur Brown's single Fire, as well as The Who's Magic Bus, Tommy, Quadrophenia, and Who's Next.
Stamp parted ways with the My Generation hitmakers during the 1970s, but he recently reunited with them for the re-release of their 1995 album A Quick One.
