Wiki definition for those not aware of the term
I enjoy a well put together Flash Mob and was just enjoying this one Som Sabadell Seasonal Flavoured Flash Mob so I had dig to see if I could get a more Traditional offering and found one though it doesn’t have full Flash Mob status nor the production values of the Som Sabell Flash Mob it’s still very entertaining. Enjoy the videos and at the end keep and eye out for more Flash Mob fun in the related videos 
Check out Commando Trad youtube videos. There are at least 10. Here’s the URL for the first one.
Very good vids thank you for sharing
Ha. I know the musicians, and a lot of the dancers. Guy on the flute was over to my place for chunes just the other day. BTW, there’s a sight for you that people might not expect to see: instead of his guitar, Dáithí Sproule with a fiddle.
Well…as in, any. At all. Flash mobs don’t get a stage and a dedicated dance floor scheduled for them. But I’m sure that shoppers were taken aback nevertheless.
