I notice Seattle is on the list! So envious! 
Nice find James!
The Scottish Boarders to Seattle is a long way to travel for a gig … but if you did want to, there are some great deals with Norwegian Air from London Gatwick to Seattle. The PNW is beautiful that time of year too.
Portland is on the list too @scott1 - that might be one for your diary!
Checking into tickets now!
Just purchased some good seats. Will let you know how it went. 
lucky you, france is a bit far from there…
