What was the piano piece from the Mark and Brian War of the Worlds?

Question

Way back in the '90s, Mark and Brian (the radio show), did a version of the War of the Worlds radio play. One of the musical interludes was a piano piece and I don't know the name. It was strictly piano, and was played over several breaks. The other piece, that was played, was Mozart's Seranade #10 in B minor. What was the other piano piece?

Answer 1

Beethoven's Barb #4 in Crescendo.
