You mean off the Decline of British Sea Power album or off the early b-sides or demos?
The earliest I have is their Remember Me CDS1 from 2001 with a decidedly different mix of that single. B-Sides were A Lovely Day Tomorrow (a great single but not as great as the Katerina Winterova versions done later in both English and Czech) and Birdy. Two acoustic demos of Childhood Memories are also among my favs, A Little Electricity and Memories of Childhood.
Let me know if you're interested in any of this stuff. Your best bet is to pick up the Japanese EPs that Jason carries at
www.theidealcopy.com - Remember Me and The Spirit of St. Louis. They're like little mini albums with some great tracks that have become real favorites.
