In June 1978, he founded the
San Francisco Gay Freedom Day Marching Band and Twirling Corps (now the
San Francisco Pride Band), which was the first lesbian and gay musical organization in the world. In Summer 1979, Sims directed the band in the first of several annual Gay Musical Celebrations for Pride Month. The Chorus made its unplanned debut a mere four weeks later, on November 27, 1978, when its members sang on the steps of the
San Francisco City Hall at an impromptu memorial for Supervisor
Harvey Milk and Mayor
George Moscone, who had been assassinated earlier that day. Sims stayed on to appoint a new director for the SFGMC, Dick Kramer, who helped helm the formal inaugural performance of the 115-voice SFGMC and the Marching Band at Everett Middle School on December 20, 1978. Sims received the
Keys to the City from then-
Mayor of San Francisco Dianne Feinstein. ==Illness and death==
