I have my Battering Ram at the ready Joe!! I know there were legalities involving the music from this one.
There are some great ones from season/series 4....Now You See Him...as you mentioned...but also Forgotten Lady and Identity Crisis......and maybe I will understand Last Salute To The Commodore a wee bit better without it having cut out scenes.....probably not...but it is just a thought.
I wouldn't expect any news from Universal for a minimum of 2-3 months, and assuming we get Season 4 on the same schedule we've gotten previous seasons, expect it no earlier than February-March 2006 since they've been following a five to six month interval between seasons so far.
