The Concert
In this Oscar nominated short film punctuated by cartoonlike sight gags, a self styled soloist performs a concert outside The Royal Albert Hall in London by "playing" the black & white stripes of a crosswalk which resembles a piano keyboard; he wins over passersby, including a constable and a group of more traditional musicians.
