Brad Ault confirmed this show!
I saw The Who in the Salt Palace, Salt Lake City, Utah on April 22, 1980. I still have my ticket stub. It was a Tuesday and the show started at 7:00 pm. Tickets cost $10.00. What a great night!
Someone in the audience lit off some firecrackers and Townshend gave us lecture about it... "If someone next to me lit off some fireworks I'd 'it 'im in the 'ead with a bot'le!" This was just a few months after the Cincinnati incident. I guess Townshend was still a little shook up.
Your set list looks pretty accurate except I remember them playing "Young Man Blues". Daltrey's mike kept cutting out and it screwed everybody up. Townshend had to pick up the beat from Kenny Jones to get the song back on track. Daltrey ended up singing "The old man's got all the microphones." You probably don't care about all this but it was a special night for me.
You guys have a great site here. I come often so, Thanks! Hope this helped out some.
