Pulp at Glasto 1995
I've never actually seen this footage before but I've got the whole show on a bootleg cd. As a huge Pulp fan knowing the entire back story that led up to this moment brings a lump to my throat. Just imagine Jarvis up there when the whole crowd goes mad just after 'I'll see what I can do...'.
Also the very human moment where he tries to be cool and tell the band to 'take it down' but had to repeat it three times before they hear him and sounds really pissed off by the third time.
