Love the idea of a big orchestra and choir. Deathtrip, Sebastian, Tumbling Down, Cavaliers, Ritz, to name but a few would be amazing.
I would would still miss some of my favourites from other albums (Red is a mean mean colour, Understand, Black & White, Nothing is sacred, All men are hungry men, Mr Raffles, The best years, and yes...make me smile)(Not that he plays them all in concert anyway).
But, with or without these 'other' favourites of mine, I would still love to see the first 2 albums performed in all their glory! A 20 minute version of Death Trip with all guns ablazing would be something to die for.
