My favorite version of PF included David, Roger, Nick and Rick, and I'd be thrilled if they reformed to record again.  Never cared much for the Syd stuff but I have immense respect for those that do.  Pulse and Delicate Sounds of Thunder are sorely missing Roger's vocals, but the situation is what it is and I am still very grateful to have a PF dvd involving the other three.  And were they generous with the extras on this dvd or what??
