Which singer from the Who appeared as Mickey Dunn on CSI?

Roger Daltrey, the singer from the Who, appeared as Mickey Dunn on CSI: Crime Scene Investigation.

Daltrey played the character in “Living Legend,” the ninth episode of the show’s seventh season, which aired in 2006. His appearance was a guest role rather than a performance as himself, making the casting connection easy to miss.

Daltrey is best known as the Who’s lead vocalist, alongside guitarist and principal songwriter Pete Townshend. The band also included bassist John Entwistle and drummer Keith Moon, but none of those other three members played Mickey Dunn. That lineup is the main source of potential confusion in this question.

Daltrey has acted regularly outside music, appearing in films, television productions and stage projects. His CSI role is one of several television appearances that followed his better-known work with the Who, including acting roles in projects such as McVicar and adaptations of The Three Musketeers.
