The enduring appeal of Rod Stewart could easily be summed up by one moment from his robust two-hour show at the TD Banknorth Garden Saturday night.
Strutting his way around the catwalk encircling his large in-the-round stage set , the faithfully rooster-coiffed Stewart started giggling. Even he couldn't keep a straight face while performing his regrettable but undeniably catchy disco thumper "Da Ya Think I'm Sexy?"
At 61, Stewart may pout and preen like some of his Hall of Fame peers but there's always been a sly nudge and wink in between the booty shakes. That cheekiness has never detracted from what has been truly great about his career -- roots rock classics like "Maggie May" and "Reason to Believe" -- and has helped mitigate what has been less stellar -- the spandex and the limp Great American Songbook records. And his awareness of his own occasional ridiculousness is a sweet poke to the audience as if to say, "Well, you guys went for this stuff."
