Good observation. I think the mid-90s he was as lively as now but the TIH era ushered in a far more restrained style of showmanship. The whole double of Jarvis to do the crowd-pleasing gestures was really a stroke of genius. A pity no quality footage from that time exists.
Were his train moves back in the day linked to lyrics about trains (though what could they be? "I'm gonna show this town who's master as soon as I get off this train"? "Pissed on a train and he's failling around"?) or just general demonstrations of personal/vehicular movement?
He does that 'train' move on New Sessions during DYWMA, I think. I actually wnet back and watched his performance at the Dolebusters gig from the Octagon of Mark Of The Devil and that's very illuminating as he kinda shuffles and twitches his right shoulder alot.
Jarv won't have wanted to answer any questions about whether they are releasing an album/touring again etc, and they're mates so JR would have known that. Plus he doesn't tend to interview the bands anyway these days.
For any Americans on here, they're showing the Jonathan Ross episode with Pulp on Cinemoi (love this channel) tonight at 1a PT/4a ET: http://www.cinemoius.com/schedule.html
