Here's a song I wrote about a related aspect, based on a true incident when I went to a session where there was noone I knew, and no music playing. And later I met someone who had been there, who'd also gone there for the session that never took place.

But the moral is, as they say, if you don't use it, you'll lose it.

The Silent Session

Oh Monday night was a dull old night
so the landlord ups and says
"I know, we're going to have a music night,
like we did in the good old day.
We'll have musicians in the public bar,
in the corner of the crowded room,
and we'll all be ready for a good old show,
and we'll have some good old tunes.

Well there was one musician had a song to sing,
and a pair of healthy lungs
but he sat there smoking of his pipe all night,
and we never had a single song. So that was one musician in the public bar,
in the corner of the crowded room -
but he sat there waiting for the show to start,
and we never had a single tune.

And there was one musician had an old guitar
on the back seat of his car -
but he never went to fetch it,
he just sat and sulked,
a-drinking in the public bar.
So that was two musicians in the public bar,
in the corner of the crowded room -
but they sat there waiting for the show to start,
and we never had a single tune.

And there was one musician had a mandolin
it was lying there in its case,
but it lay there silent underneath his chair,
while the evening was going to waste.
So that was three musicians in the public bar,
in the corner of the crowded room -
but they sat there waiting for the show to start,
and we never had a single tune.

And there was one musician had a fiddle and a bow
and a head so full of tunes
but they all sat there, waiting for the show to start,
like a family of old baboons.
So that was four musicians in the public bar,
in the corner of the crowded room -
but they sat there waiting for the show to start,
and we never had a single tune.

And the landlord said "Time Gentlemen!"
and he sent them on their way.
"That's the very last time we'll have a music night
it seems there's nobody as wants to play.
But we were all musicians in the public bar,
in the corner of the crowded room -
but we sat there waiting for the show to start,
and we never had a single tune.

So now come all musicians in the public bar,
in each corner of the crowded room -
don't you sit there waiting for the show to start,
when you can start it with a good old tune.
