Uncle Tone: I remember putting on Gilmore and Roberts at a venue in Sevenoaks a few years back, with a local "folk-rock" band as support.
I was quietly happy that I'd broken even on the evening when I got a letter from the venue with a request that I fill out a list of the sets of both support and main artistes.
The support performed all their own songs, and Katriona and Jamie performed 2 arrangements of trad songs. The rest were their own. I still had to give the venue £36 for the PRS....and since the "take" at the PRS overwhelmingly goes to those who need it least, I felt a bit annoyed that famous musicians would actually be benefitting from these young performers doing their own songs!
And I ended up losing a few quid on the gig.
