Thanks to the internet there's really no such thing as a rarity anymore. If a song's been released (even if only on vinyl) the chances are that it's on the net somewhere. I've seen a number of vinyl only Tim songs that some kind soul transferred into MP3s and put on the net. The bottom line is that now-a-days either it's been released or it hasn't. If it's already out there those in the know who actually want it will already have it. On the plus side this collection does have a couple songs that were not previously released and therein lies its true value.
