I’ll just throw out a few off the top of my head (Some may not be the actual titles)
“Powerhouse” of course (The industrial music)
“The Barber of Seville”
“I’m looking over a four leaf clover”
“We were sailing along”
“Baby Face”
“Hello ma Baby”
“I’m Just Wild About Harry”
Fingal’s Cave (Die Fingalshöhle), composed by Felix Mendelssohn
That Mina bird walk tune was unforgettable and got me to love the work of Mendelson. Nowadays the Mina Bird shorts are not shown much as the main character was Inki, a pigmy with a very stereotyped look.
Oh yeah. Morning is a popular one in cartoons. I hear In the Hall of the Mountain King every once in a while (a bit is in the theme of “Sonic the Hedgehog”), and March of the Dwarves shows up sometimes too.
I can’t hear “You Must Have Been A Beautiful Baby” without singing it in Elmer Fudd’s voice, ending it like a singing telegram (“signed Miles Standish”), and demanding payment.
And along the lines of Dale Sams “quack quack” to “The Blue Danube,” I cannot hear Brahm’s Lullaby without singing, “Go to sleep, go to sleep, close your big bloodshot eyes…”
