Yes, absolutely. I have a story and I hope it's not too (tl/dr) long and boring, but back in 2003, my family and I went on an extended trip through Central Europe, staying mostly in Romania and the Czech Republic, with some time in Hungary.
In case I sound like a rich person, we sold everything of value we owned to do this, including computers, vehicles, etc. We thought it might be our only shot at a trip like this.
Anyway, we were traveling (rented a car) between the towns of Brasov and Sibiu in the upper part of beautiful Romania and it was getting to be evening, we needed a leg-stretch...so we came upon this inn/gas station/little store that was literally in the middle of nowhere in these beautiful big hills.
The only instrument I had with me on this trip was a steel-bodied resonator ukulele.
Well, as we pulled up to the place, there were three older gypsy guys sitting at a table out front having a little jam session. One guy was playing concertina, one was playing something like an oud, and one was playing a Django-style nylon string guitar.
While my wife and kids were inside, I broke out the uke and raised my eyebrows as if to ask "Can I join in?" Their eyes lit up, they offered me a seat and some beer and they proceeded to start playing. Unusual scales, unfamiliar melodies, but I was able to join in on some chording and even a bit of soloing. We were all laughing and cheering each other on.
After several minutes of this, they looked at me and one of them sort of pointed at me with an open hand and I started in on some old country blues number. They fell right in! We ended up playing quite a while, different things from old American folk tunes to some real gypsy jazz sort of stuff. By this time my wife, kids and other people from inside the place were outside at tables watching and listening.
I've played hundreds of gigs, but this may have been my favorite "live" music making experience ever. It was (not to get overly cheesy) magic.
I knew about a dozen words in Romanian and I think these cats knew even less English, but yes--we communicated for sure.
