Nearly 100,000 people, not all inside the stadium, turned out for The Who's farewell concert in Philadelphia.

Roger Daltrey was resplendent in a turquoise dinner jacket.

The charged-up throng of teens and young adults at JFK Stadium Saturday neared the 100,000 mark, counting the thousands of ticketless music fans who listened to The Who in their last Philadelphia concert appearance from a vantage point in the parking lot. It seemed as if a lot of people with tickets to Friday's canceled Who show still showed up at Saturday's sold-out concert with the hope of gaining admission.

Consequently, conditions were a bit tense at the overcrowded and understaffed stadium entrances. (Has the lesson of The Who's Cincinnati disaster, in which 11 people were trampled to death, already been forgotten?) Later, a true danger developed when front-row standees were pressed into the chain-link fence protecting the apron of the stage. Guards responded by dousing the overheated crowd with water, or by pulling claustrophobics over the top of the fence to safety.

And yet, when fed with the proper rock 'n' roll anthem, this crazy quilt of humanity cooled out, singing and clapping with electrifying enthusiasm to such Who classics as "Behind Two Eyes," "Baba O'Riley" and "Won't Get Fooled Again."

Visiting JFK Stadium as the third date on its "farewell" U.S. concert tour, The Who seized the occasion with a tight, well-rehearsed, two-hour and 23-song set that stretched from "Substitute" to the moldie-oldie "Twist and Shout."

Included were special nods to the classic "Tommy" and "Quadrophenia" albums, and the obligatory plugs to the new Who LP "It's Hard," bested by the funky "Eminence Front" and the guitar-powered, rock march "Cry If You Want."

As to speculation that The Who, godfathers of British Punk Rock, are cutting all touring after this year because they simply can't cut it anymore, it just isn't so. Guiding light Pete Townshend looked to all the world like a trim and trendy 25-year-old in his close-cropped haircut, head band and black leather jacket, sleeveless T-shirt, jeans and sneakers. And he acted the part with his patented scissors jumps (only one slip), windmill guitar strums, and sparkling instrumental passages, which inevitably brought a fast huzzah from the crowd.

Lead singer Roger Daltrey and bassist John Entwhistle could have just stepped off an ocean cruise, resplendent in their turquoise and purple (respectively) dinner jackets.

Drummer Kenny Jones does not pretend to be his predecessor Keith Moon, thank heaven, but he still manages to thrash away at his percussion kit with a rocket-fueled propulsion that says "Who else but The Who?"

Philadelphia's excellent ska-rock band The Hooters opened the show earlier than expected (11:15 a.m.) followed a little after noon by Santana, which overcame recurring sound-system problems to win the roaring approval of the crowd.

Britain's reigning punk kings The Clash — clearly out of their element in the daylight, and nervous to be slotted directly before The Who (a major influence on their career) — played a relatively brief, 40-minute set with no encores. The audience responded best to numbers they'd already heard on the radio — "Rock the Casbah" and "Should I Stay or Should I Go." When The Clash were laying on their political lines, the stadium's rotten acoustics swallowed most of the meaning.
