On the Who 's 1979 tour , only four songs were played live : " Sister Disco " , " Music Must Change " , " Trick of the Light " , and " Who Are You " . On that tour , " Sister Disco " was played quite close to the studio version , except that the guitar outro was changed from country-style to a more bluesy one , except in 1989 , where Townshend used acoustics , and 2008 – 09 , where he could switch his Fender from ' electric mode ' to ' acoustic mode ' . Townshend actually stated in an interview that this was one of his least favourite songs to perform live ( the other being " Dreaming from the Waist " ) , as Daltrey encouraged Townshend to share a microphone whilst harmonizing on the final vocal tag , evoking a camaraderie Townshend stated did n't really exist . It was played in the tours of 1979 , 1980 , 1981 , 1982 , 1989 , 2008 and 2009
