Open Fifth Puns

Every year for the past few years, I’ve written music for a tuba ensemble for a summer band camp. Last year’s music was titled “TubaChristmas in July,” which had “Hallelujah” by Pentatonix, “Carol of the Bells,” “You’re a Mean One, Mr. Grinch,” and “Have Yourself a Merry TubaChristmas.” This year I’m about 90% sure we’re doing rock/classic rock. So far I have “Bohemian Rhapsody” by Queen, “Paint It, Black” by The Rolling Stones, “Livin’ on a Prayer” by Bon Jovi, “Don’t Stop Believin’” by Journey, and some fifth song I haven’t chosen yet (BTW I’m open to song ideas).

I need a pun that mixes Tuba with Rock or with Classic Rock. Similar to how TubaChristmas in July doesn’t include song names, but you know it’s Christmas music on tubas.

A C, an E-flat, and a G go into a bar. The bartender says: "Sorry, but we don't serve minors." So, the E-flat leaves, and the C and the G have an open fifth between them. After a few drinks, the fifth is diminished and the G is out flat. An F comes in and tries to augment the situation, but is not sharp enough. A D comes into the bar and heads straight for the bathroom saying, "Excuse me. I'll just be a second." An A comes into the bar, but the bartender is not convinced that this relative of C is not a minor. Then the bartender notices a B-flat hiding at the end of the bar and exclaims: "Get out now! You're the seventh minor I've found in this bar tonight." Eventually, the C sobers up, and realizes in horror that he's under a rest. The C is brought to trial, is found guilty of contributing to the diminution of a minor, and is sentenced to 10 years of DS without Coda at an upscale correctional facility.
