Busking At The Supermarket

Mark McAllister loves to play music, and you can hear him perform if you're shopping at Nob Hill Grocery on most days. He can usually be found standing between the store and Peking Tokyo restaurant.

McAllister specializes in old timey music, but can also perform more modern material. He's been playing and singing most of his life.

Here McAllister is seen performing the classic "Roly Poly."
