Wow, well first, welcome. It's nice to see a new post up in this piece.
As far as a longer version of Two Girls, I'm not quite sure what you mean. Drop a link to the Youtube version you were digging and I'll take a look. I'm at work right now or I'd search for it myself. If nothing else I can at least make you a rip of the audio from Youtube.
Also, you may be aware of it, but Dave and Jon (lead singer and bassist for PSC) are on hiatus from the band right now while they work with their former band Rustic Overtones. Check them out if you get a chance and if you like what you hear, come join us over at Rocklikewar.com.
