Well, tell that to Iron Maiden - they have 16 albums to choose from now and they barely ever change setlists! British Lion has one album out. One album. Two new songs is a big change then. They're playing, what, 5 songs that haven't been released yet? What should they do, covers? What's the point, from Steve's point of view, to go out and play Maiden-songs with BL when the whole point, from the beginning, was to get away from what Maiden was doing (along with helping friends out a bit etc.)? It just does not make any sense as he's doing it alongside Maiden. Would be a different matter entirely if Maiden had retired 10 years ago.
We will get new songs when the album is out. As it is now, they need to tour to have any hope of keeping this little band alive.
