For the problem with gaps try
foobar 0.8.3 special. There are newer version of this music player available but this is the only version which has the 'gap killer' plugin. I use it to play badly encoded mp3s and the gaps are gone!
The original Born Slippy from that gig is simply the best live track i've ever heard and was my favourite on the Bootleg Babies. I think it is a very special moment when they play that song because it's never the same. Sometimes they perform the 'single' version (like on the radioshow in december), sometimes a kind of 'dancey' version like here or something slightly different (ahoy).
ohh, i want to hear them live so badly! (stupid Movement festival... Frankfurt on the horizon...!)
