The Who’s musical career spans four decades — and it shows.

Pete Townshend, Roger Daltrey, John Entwistle and company performed the Quadrophenia album and other goodies for an enthusiastic crowd at the Blockbuster-Sony Music Entertainment Centre on Wednesday night. Gone is the furious rock band that smashed guitars and drum kits at the Marquee club in London in 1963. Or the band that ripped up the stage at Woodstock.

The original members are still rocking, but not as powerfully as they used to perform. The veterans were supported by terrific players, like Ringo Starr’s son, Zak Starkey, and a five-piece horn section.

For almost 1½ hours, the band played Quadrophenia in its entirety. Released in 1973,

REVIEW

Quadrophenia is Townshend’s underrated rock opera about a teen-ager named Jimmy coming of age in London in the days of the mods and rockers of the early 1960s.

The 13-piece band opened powerfully with the opera’s “Overture,” as the audience is introduced to Jimmy, who talks via a movie screen behind the drumstand.

The crowd sang along with most of the album, even the lesser known numbers like “The Dirty Jobs” or “Is It in My Head.” Although Daltrey looks in great physical shape, the singer did not hit the high notes.

Townshend showed off his acoustic guitar skills in numbers like “Cut My Hair” and “Drowned.”

But fans who were waiting for Pete to play solo had to hold out for some time. He played rhythm most of the night and let his brother Simon take the lead parts. Simon Townshend was solid, and when he sang harmonies with his big brother, it was fabulous.

Musically, this wasn’t the same band that rocked JFK Stadium in 1982, however. It was thrilling to hear “Sea and Sand” played live, although the version wasn’t earth-shattering.

The band has been playing this album for more than one year. Maybe they’re sick of it.

Did they just stop caring? Let’s hope not.

The band closed the show with Daltrey and Townshend playing an acoustic version of “Won’t Get Fooled Again.” The band plugged in for a few more numbers, “Behind Blue Eyes,” “Substitute,” “I Can’t Explain” and “The Kids are Alright.” And they closed with their anthem, “Who Are You?”
