You'll need a program capable of playing mp3 format files (e.g. WinAmp) to listen to the music.
About the songs...
Both of them are original compositions, the work of our two guitarists. Rob wrote "Pictures..." and John wrote "If It's Easier..." The decision to play "Pictures..." in the concert was a last-minute one. We worked out the details in a panic-filled evening rehearsal, in the knowledge that we'd have to get it right later that night. I think it worked out pretty well.
As for "If It's Easier...", this was probably our favourite song. We always enjoyed playing it, so we saved it for the grand finale.
Give them a try.
