I had the chance to see BRIT FLOYD Echoes play in 2012 and it is true that this performance is superb. Echoes was already on the 2011 tour I think (DVD)
I think it's good to submit titles to the group for 2015 tour, but do not put pressure; Echoes is a long way, so its integration or not is a crucial choice on a program that BRIT FLOYD wants new every year, and they were able to concoct many good sets lists so far.
I think you have to trust BRIT FLOYD, they have good ideas and will pleasantly surprise us in 2015, especially as it will be a great tour.
