Yep, I do now. Like me, my brother learned to play some keys and guitar when he was in college but hardly touched for several decades - and he's 10 years older than I am. Earlier this year he bought a nice guitar and start taking lessons and is making pretty impressive progress for such an old fart (he's 64).
He lives about 1000 miles away but he intentionally does marketing for contracts in this area so he can visit our parents while he's here on business. When he does that, he usually plans to stay one night at our house so we can jam a bit. Not only does he use my Strat, which I've hardly touched in 15+ years, I also bought a decent amp so he has something to play through when he's here.
I've also talked to a friend at work who's planning to pick up guitar again after a long break, so I told him I've already got gear at my house if he wants to start playing together.
