Pub songs ?

From the 1940s to the early 70's my uncle used to take his accordion,
or in later years his portable electric organ, to his local boozer
and lead a singsong of old standard pub songs.

I don't know the format, because I was too young at the time.

It might have been skittles or darts night;
or it might have just been an informal session whenever folks were in the mood.
Doubt if they ever sang any trad folk songs, unless any were popular communal singalongs ?

..and I'd hazard a very strong guess none of the regular drinkers ever wrote any of their own original songs...

Uncle certainly wouldn't have even thought to call himself a 'folk' singer.

So was it 'Folk' ????

Thinking more about it, there was a weird beatnik looking young bloke with an acoustic guitar
who sang 'There was an old woman who swallowed a fly" as his party piece...

Saw him perform once at an early 1960s kiddies birthday party..
don't think I liked it much...????
