Bad Ol' Putty Tat--musical question

[larriva9/11]

Someone remind me again what the music is that accompanies Sylvester's contented stroll before Tweety turns him into a choo-choo train? (i.e. the melody that sounds like and presumably influenced "Hey Jude")

It's from the overture to the opera Ruslan and Lyudmila (http://www.youtube.com/watch?v=HX-gR-zzZgc) by Mikhail Glinka. (The opera isn't performed much outside of Russia, but the overture was a very popular concert piece.)
