Umm indeed I have a barking mad uncle who is not many years older than me he is a jazz drummer and so I had free access...fab, we had some terrific sessions at a family run hotel where bods who had not seen eachother for years would just rock up and play, oh and drink vast quantities of callapso for the entire weekend. Pretty good with a tea chest a large rubber band and a broom handle myself,though I couldn't possibly say at what. 
These uncles can be quite influential; I had one - sadly died a few years ago - who was a real Gent, ex Grenadier Guards, moustachioed, a stickler for all things proper and British, manners, deference and the establishment. He also had a passion for jazz!
.
So much so that he spent most of his army career in the jazz band playing practically everything performed by Django Reinhardt. I'd go and see him in his retired years and was amazed to find that he'd set up a music room with all his guitars, amplifiers, speakers and the obligatory bottle of scotch
He'd pour a couple of large ones, hand me one of his rhythm guitars, pick up his Maccaferri, tell me the chord sequence and off we'd go!
