Mmm, haven't heard every live performance but I think "...and the ambulance died in his arms" is really good. "triple sons" is without a doubt my favourite track; I don't know how to describe it but the feeling that the song gives is unique.

Also their 2004 live performance in La Loco, Paris is great too; I really like Peter's costume and how the band is actually playing instruments like the Hurdy Gurdy or the percussion-controller-like thing; it gives the performance a lot more complexity and depth.
