With the jukebox musical of the Four Seasons story, Jersey Boys, a runaway success, interest has been renewed in the vocal group who delivered a bevy of hits in the '60s such as ''Sherry,'' ''Big Girls Don't Cry'' and ''Walk Like a Man.'' Now 79, the sweet lead falsetto behind those tunes, Frankie Valli (with some much younger Seasons), will team up with the Houston Symphony for a night of nostalgia. And for Valli's music director, Robby Robinson, it's a natural fit. ''A lot of the original Four Seasons recordings incorporated strings, horns, woodwinds, harps and other instruments. And [Valli's] music covers pop, R&B, jazz and doo-wop,'' he says. ''And with other songs, we've had fun [tinkering] with, like adding bassoons and pizzicato to 'Walk Like a Man.''' Robinson also notes that the Houston Symphony is a ''brilliant orchestra,” since Valli and the Seasons have performed with them in the past. He also sees the more-and-more-frequent pairing of pop and rock acts from the '60s and '70s with orchestras as a natural development. And who knows? They may even tackle the theme from Grease.
