At this famous concert Keith Moon slumped over his drums. Dave Marsh wrote:
"The band crashed into the song (Won't Get Fooled Again, K.J.), but after only
a few bars, Keith Moon slumped over his drums ...The roadies carried him
backstage into the dressing room, where he was placed in a cold shower and
revived ...
After another half-hour's delay, the Who once more hit the stage. Moon proclaimed
himself fit, and the rest of the band tried valiantly to pick up where they'd
left off. But Moon was too weak to continue - he didn't even get through the
first song. He was taken backstage and then to the hospital ... Meanwhile,
Townshend was enraged that the beginning of the tour was so disastrous.
'Hey,' he shouted to the crowd. 'Can anybody out there play drums? I mean good.
Any takers come up here onstage.'

Scott Halpin, a nineteen-year-old ..., fought his way over to the security guards
and tried to talk his way onstage... 'It all happened really quick,' Halpin told
Rolling Stone. 'I didn't have time to think about it and get nervous.' Townshend
introduced him (as 'Scott'), called for Naked Eye, giving Halpin the time
signature, and they were off. The Who ran through two other songs, 'Magic Bus'
and 'My Generation,' before finishing.« (Dave Marsh, Before I get old - The story
of The Who, Side 430). I can't confirm the songs Dave Marsh listed. According to
my researchs The Who played Smokestack Lightning and Naked Eye with Scott Halpin
on the drums.
