[Trombone-l] Repair Q in re Out of True Leadpipes

[Walter Barrett]

This is something that John Upchurch has remarked on in the past. If  
you give him your slide work, it's definitely worth it to include the  
leadpipe with the slide. I'm sure he can deal with it if it's out.

John's local enough to you that it'd be worth a trip to demonstrate it  
in person.
