Bring her head round, now all together

An early blip today despite the fact that I'll have far more blipping opportunities today.
I take it this is an Edinburgh coastal rowing club getting in some practice before the regatta in Dunbar on Sunday (see 28th May entry).
I took a lot of pictures but only had one lens with me so nothing closer.
In fact I took so many pictures that if I flick quickly through them I get a small cartoon.
I don't know if they sing but it could add an entirely new category for the regatta.
