This was Groucho's second time hosting this show.
Also appearing are his 18 year-old daughter singer Melinda Marx
entertainers Gordon & Sheila MacRae, and comedian Shecky Greene.
This was the last appearance anywhere of Margaret Dumont,
the popular straight-woman in several Marx Brothers movies.
She came on Hollywood Palace at Groucho's request to again play her
most famous role of Mrs. Rittenhouse. It was just 8 days before her death
in February 1965. The show aired a month later.
