Singer Roger Daltrey of The Who regales a sellout crowd of 80,000 Sunday in Rich Stadium.

The Who were all right Sunday afternoon in Rich Stadium. And so were the kids — 80,000 of them, drawn not only from Buffalo, but from Rochester, Syracuse and Toronto for this fifth show in what’s been announced as the last tour by the veteran British supergroup.

While there seemed to be no major hassles inside the stadium during the concert, police and sheriff’s deputies arrested at least 22 people outside on a variety of charges and contended with a large traffic jam that clogged highways around the stadium for miles after the show.

The crowd inside the stadium, remarkably well-behaved and undaunted by a twilight shower, burst with undiminished cheers and enthusiasm throughout the band’s 2 1/4 hour stint on the huge stage set up at one end of the tarpaulin-covered football field.

They yelled best for the old tunes and the old moves. A deep roar greeted the familiar intros to such favorites as “Who Are You” and “Behind Blue Eyes.” Shouts egged on the antics of singer Roger Daltrey, who twirled his microphone like a red-hot yo-you, and guitarist Pete Townsend, who flailed windmill-like at his power chords.

The Who knew just what the crowd wanted. As a band that has spent nearly 20 years examining and justifying the outlaw ethics alienated youth, they aimed straight for the heart of the issue — the question of appearance vs. reality — in the dislocated refrain of their opening number, the ’60s hit “Substitute.”

Within half an hour, they’d tapped into their ultimate rally cry, the proclamation of “teen-age wasteland” in “Baba O’Reilly,” with a stadium full of kids shaking their hands above their heads in time to the chords, singing that magic phrase with all the strength and resonance they could give it.

That resolved, they settled down to party, but not with a review of the Who’s greatest hits. There were new songs from the latest album, “It’s Hard,” and a few similar-sounding unreleased numbers worked up for what’s expected to be a live album taken from this tour.
