The Who finished their concert at the Cow Palace in Daly City, California, on November 20, 1973, with an audience member playing drums after Keith Moon collapsed onstage. Scot Halpin was 19, a fan attending the opening American date of the band’s Quadrophenia tour. Before the evening was over, he would be playing part of the set himself.
The crisis came late in the performance, after the band had played its Quadrophenia material. Moon collapsed during “Won’t Get Fooled Again” and was taken offstage. He returned but collapsed again, leaving the group without its drummer. Pete Townshend appealed to the audience for someone who could play.
Getting Halpin onto the stage took some persuasion from his friend Mike Danese. In an interview with Phil Hood, published by DRUM!, Halpin recalled his friend pushing him forward until promoter Bill Graham asked whether he could do it. Graham brought him backstage and handed him to a drum roadie. By Halpin’s recollection, he was already behind the kit while Townshend was asking the crowd for help. Roger Daltrey learned his name and introduced him.
Moon’s equipment presented an immediate challenge. “The tom-toms were as big as my bass drum,” Halpin recalled. Cymbals overlapped, and the drums were locked into position. He turned his sticks around to strike with their thicker ends because he wasn’t getting enough sound. Poor monitoring left him relying on what he could hear acoustically from the kit.
Townshend helped him follow the music by promising to give him cues, Halpin told the San Francisco Chronicle in 1996. The closing stretch included blues material and The Who’s “Naked Eye,” taking the substitute from the audience into an unrehearsed performance with the group. When the music stopped, he joined the musicians for the final bow.
The evening also left a visual record. A two-camera system captured the concert in black and white, and the recording formed part of Graham’s personal archive. Footage of Moon’s collapse later appeared in the video collection Thirty Years of Maximum R&B Live.
Halpin continued making music and visual art after his brief appearance with The Who. He played in other groups, managed a rock club and worked as a composer-in-residence at the Headlands Center for the Arts in Sausalito, California. After his death in 2008, aged 54, his family began gathering the artwork and recordings he had left behind.
Townshend remembered their brief collaboration, too. After Halpin’s wife contacted his office about the death, the guitarist sent a message for the memorial. As Classic Rock later recounted, Townshend praised the courage and humor Halpin had shown when he took over at the Cow Palace, remembering him with gratitude and affection.
