I remember an old movie (looks like Technicolor) where there's fairies living in a tree, the male fairies run around trying to catch the females to marry them, there's a normal-sized man (possibly burl ives) who sings to them with a guitar. What is this movie? Thanks!

Pretty sure you're looking for this:
The Gnome-Mobile (1967) - IMDb (http://www.imdb.com/title/tt0061715/)
(pretty sure... )

YOU'RE MY HERO!! Thank you!
