That (Borodin blasting) was UN-repaired condition (the bell was folded back, and the bottom bow was so flattened, that I believe I could have stood it up on the bottom bow), and super-clanky...out-of-the-shipping-box condition.
(During one of those rehearsals, I turned the bottom of the tuba towards the trumpet players and asked them if they thought my "new" tuba was a little flat.)
The bass trombone player made that video with his tablet.
I thought it was pretty dang funny, so I stuck it with my youtube stuff.
I have a (bad?) habit of taking newly-bought/un-repaired stuff to gigs.
Before I totally revamped that compact Holton B-flat, I took it (clanking, old corks/old felts, and same-day-as-received-from-USPS) in THIS condition to a one-hour outdoor quintet concert. (The host was horrified...It played fine...It was dark out, and no one could see it, anyway...All we had - for lighting - was/were stand lights.)
