Patty, I guess I read the thread title differently. I took "Pretty waltzes with lyrics" to mean "pretty melodies that also have lyrics to them." In other words, I was focusing on pretty waltz tunes, not pretty poems set to waltz tunes.

As for Rosin The Bow, there are dozens of songs set to it.

If we're also looking for "pretty lyrics," do they have to be inspirational or romantic poetry for the lyrics to be "pretty?"
(I kinda like "Stewball.")

Other pretty waltz tunes that have nice lyrics are:

MR BOJANGLES

A DAISY A DAY (Jud Strunk)

TRY TO REMEMBER (also from The Fantasticks)

Wish Me A Rainbow
