I watched part of Horse Feathers and then all of Monkey Business, A
Night At The Opera and A Day At The Races.

In Monkey Business, I saw something that I never noticed before. When
Harpo is backing up Mrs Schmalderhausen's opera solo at the party on
harp, he appears to be thumbing his nose at her while playing the harp.
Meanwhile, one of the other musicians is cracking up laughing as he is
watching this. It just shows as many times as you watch these films,
you can still see something new and funny........ I hope everyone had a
Happy New Year................Pete
