That’s it! Thanks.
The same gag (and tune) was also used in the Private Snafu cartoon “Booby Traps”.
As a kid I heard it as “Oh the sheer, sheer delights”.
From the post…
“Since the people here are so good at naming Looney Tune songs, what is the song that Daffy rigs the piano to blow up when a certain key is hit and Bugs keeps playing it wrong, enraging Daffy who plays it correctly and blows himself up dead?”
I remember this cartoon well. My sister and I took pi-anna lessons when we were kids. It was Yosemite Sam who gets blown up by his own device.

From the link…
Sam rigs explosives in the piano, attached to a specific key, and presents the piano to Bugs to play “Those Endearing Young Charms” (a gag recycled from a Private Snafu short).
You can even see the title “Endearing Young Charms” on the sheet music in the cartoon.
Or hoist by his own petard!
SNAFU = Situation Normal, All Fucked Up!
TARFU = Things Are Really Fucked Up!
FUBAR = Fucked Up Beyond All Recognition!
Looie = Lieutenant
Topkick = Master Sergeant
Pot = Toilet
That was good!
I like Mitzi Mayfair (the little one on the left).
