I've heard Fathom the Bowl a few times over the last few years. Especially at the more chorus-friendly singarounds. I would say I hear it as often as songs like Let Union Be - that bunch of 'everybody have a drink or two in the spirit of conviviality' songs. Much missed in covid times!

I'm not surprised you don't hear Firelock Stile or Furze Field all that often, can't see the appeal in them myself.

Lord Thomas & Fair Eleanor is a good one to raise. I "think" I've heard it at singarounds, or a version of it, but I may just be imagining that as it's a song you inevitably end up reading fairly frequently when browsing songbooks.

'Twankydillo' is a song I've sung a few times at singarounds and had a few older people comment they'd not heard it sung for decades. Probably cos of the silly sounding word.

I remember going to a singaround pre-lockdown that happened to take place 'the week before Easter'. And we ended up with 4 different versions of that song being sung, due to latecomers not knowing that others had already sung it earlier. They couldn't understand why some people were trying hard to suppress giggles when they started singing the first line... It reminded me strongly of a PG Wodehouse Jeeves & Wooster story with a similar situation.

I'd be interested to hear of any traditional songs that nobody has EVER heard anyone sing? (Not counting 40+ verse ballads, for obvious reasons)
