Topic: Marx Brothers
Harpo Marx plays "I'm forever blowing bubbles" on the Kraft Music Hall in 1959 with "Mr. Television" himself, Milton Berle. Harpo also plays the harp. File under bubbles and The Marx Brothers.
Chico Marx plays the piano (and an apple) for his brother Harpo in this 1940 clip from the film Go West. There are more classic clips and more Marx Brothers in the archives.
From 1933, the classic mirror scene from The Marx Brothers’ Duck Soup. (A great DIY comedy activity, too!) Thanks, @MichaelGTV.
Harpo Marx playing his harp in A Night in Casablanca (1946). Beautiful close ups of the strings, and it picks up tempo in the last minute. There are more Marx Brothers clips in the archives.
