 Moon 's lifestyle began to undermine his health and reliability . During the 1973 Quadrophenia tour , at the Who 's debut US date at the Cow Palace in Daly City , California , Moon ingested a mixture of tranquillisers and brandy . During the concert , Moon passed out on his drum kit during " Won 't Get Fooled Again . " The band stopped playing , and a group of roadies carried Moon offstage . They gave him a shower and an injection of cortisone , sending him back onstage after a thirty @-@ minute delay . Moon passed out again during " Magic Bus , " and was again removed from the stage . The band continued without him for several songs before Townshend asked , " Can anyone play the drums ? – I mean somebody good ? " A drummer in the audience , Scot Halpin , came up and played the rest of the show .
