I came across this somehow
A Guinness World Record-Setting Event for Banjo Players!
…
We plan to bring together the most number of banjo players assembled at one location to play the same song at the same time.
…
All banjo players are welcome to attend. Only those who can demonstrate the ability to play the song Foggy Mountain Breakdown for 5 minutes will be counted toward the Guinness World Record. The tempo will be 120 beats per minute, and we’ll play in the key of G.
…
We’ll stand together on the field in small teams, according to the type of instrument played and the style of play.
That’s a whole lot of banjo. I have all the usual bluegrass prejudices against the banjo I suppose.
