WHO stirred a breeze in the Cellar Thursday, a night so hot that abandoned paper cups crumpled up by themselves.

The Who, a British pop rock group, appeared at the Arlington Heights teen club between a Detroit date and the upcoming Monterey [Cal.] Pop festival.

After 20 minutes of electronic troubles, the four launched their show with "Substitute"—friendly Keith Moon lighting up on drums, kinda sarcastic Roger Daltrey on vocals and theatrics a la James Brown; businesslike Peter Townshend, who writes a lot of Who's songs, on lead guitar, and John "hostile man" Entwistle on bass guitar.

The show was too short [15 minutes] because of the mechanical troubles and the Arlington Heights curfew—but it was sweet and loud. The four worked well together, with good instrumental balance. Some gutsy guitar and vocals stood out particularly on "Happy Jack," their current hit here.

and which Keith says has put them in big debt. "Antonioni offered us the guitar smashing bit in the movie, 'Blow-up,'" said Keith, "but we had a club date at the time. So they used the Yardbirds, who copied our bit."

After the show, a fan asked Peter what he'd do for a guitar tomorrow.

"Glue it back together," he answered.

With an act like that, what do they do for an encore?
