HARTFORD – The Who's Tommy may have found his miracle cure in a smashed mirror, but for Roger Daltrey the secret to good health may be as simple as "no smoking" signs.

Daltrey, who has battled vocal woes in recent years, was in fine form for a solo performance of The Who's rock opera "Tommy" at the XL Center Saturday night. At a few points in the first half of the night, his voice did catch. The Who singer blamed the frog in his throat on secondhand smoke from the audience.

"I have developed a terrible allergy to cigarette and marijuana smoke… If you'll stop smoking, I'll keep singing," Daltrey told the few thousand fans in attendance shortly after the final notes of "Tommy" sounded.

True to his word, Daltrey performed another 12 songs, ranging from a moving cover of Taj Mahal's "Freedom Ride" to his own "Days of Light" to the searing "Young Man's Blues," which rivaled the take he recorded with The Who for the "Live at Leeds" album 41 years ago. His voice sounded stronger as the smoke cleared and the evening progressed.

Looking fit and trim, the 67-year-old Daltrey began the night with a near-complete performance of the landmark rock opera "Tommy." He wisely chose to eliminate the 10-minute instrumental "Underture" from the middle of the lineup.

As he has done in the decades since the release of "Tommy" in 1969, Daltrey whipped his wired microphone during songs like "Amazing Journey" and brought the crowd to its feet with impassioned takes of "I'm Free" and "We're Not Gonna Take It."

With fellow Who band member Pete Townshend not touring this year, Daltrey is fronting a tight band that replicates The Who's classic sound. Townshend's younger brother, Simon, played guitar and handled lead vocals on "It's a Boy" and "The Acid Queen," the latter of which was particularly well-received by the crowd.

In the second half of the evening, Simon Townshend nearly stole the show from Daltrey with his take of his brother's "Going Mobile," a Who favorite that, strangely, is not a concert staple.

There were two misfires during the night. A tepid "Who Are You," and an abbreviated and reworked "My Generation" failed to match performances of those numbers during recent tours. However, fans could rejoice in Daltrey's rock solid performances of "I Can See For Miles," "Pictures of Lily," and "Baba O'Riley."

Daltrey ended the evening with two lesser known numbers: "Without Your Love" from the soundtrack to his 1980 movie "McVicar," and "Blue, Red and Grey," a 36-year-old Who cut he chose to perform on ukulele.
