Aw, I love "Canon"
I always thought I would use the theme from Somewhere in Time (Based on Rachmoninoff's Theme from Paganini) as the enterance music for the bride, "The End" by the Doors for me and Carmina Burana as the exit music. First dance would be a Chicago song.
Oh well, a guy can dream right?
