I remember my Father buying me this on vinyl in 1982, so it will always be special.
One of the main reasons was to have Going Underground on a LP.
The Jam simply generated energy whenever they played live, lots of great feedback from Paul's Rickenbacker, Bruce's always solid Bass covering the lack of another guitar on stage and the other part of the great rythmn section is Rick's understated Drums.
I would even go far to say that the tracklisting on this album which rather than going for all the commercial singles, goes for some of those great album tracks, Sound Affects 'Set the house ablaze' I think is better live than on that great album.
'Standard's' from Modern World is another with the simply lovely crowd participation on 'Ghosts' from The Gift is another gem.
A hidden gem here is the great cover 'Big Bird' which is the only Jam album to find this track on.
Sadly I never got to see the Jam Live, but this goes some way in having a momento of how great they were.
