Stan Laurel was the skinny, head-scratching halfwit; Oliver Hardy was the hefty, haughty fella with the pipsqueak moustache. As seen in their Hal Roach-produced heyday, the legendary Laurel and Hardy have always been moving pictures' quintessential odd couple. This weekend, the Old Town Music Hall celebrates the pair's antics with a collection of both their silent and sound-laden classics, with musical accompaniment by Mighty WurliTzer to lend the proceedings a bit of old-time authenticity.
