Strumming Sorrow

Grateful am I, for your aid's in sight, please hurry and take flight!

Oh, my! You actually found the receipt?

Well, well, aren't you the persistent type?

I must admit, I didn't think you'd find it.

Now, here's the deal: no refunds, only exchanges.

I'll take the guitar, if you can help me find Felix... something else.

I strum and I hum, I can't stop this dumb tune! Bart sold me this guitar, it's my endless doom!

My fingers are sore, my voice is all cracky; every time I play, it feels more like... shitake!

Bart's deal was too sweet, but now I'm beat, can you find the receipt? It's in a nearby seat!

Check the bars around, receipts might be found. Please, end this sound, get me uncrowned!

Oh drat and dribble, I'm stuck with this quibble!

Can't stop, won't stop, until my heart will flop!

My hopes dashed, my tunes thrashed!

Guess I'll croon another moon, as doom looms soon!
