Pretty much all Genesis fans want a full Lamb performance, but it doesn't exist. You may have to check out cover band The Musical Box, as they've recreated The Lamb shows with incredible authenticity.
I do want to pick up this When In Rome DVD, but as I hate double-dipping, I'll likely wait for the Blu-ray. (Not that I even have a BD player yet, but I will. Oh yes. I will.) Unless I find a copy at a ridiculously great price, that's the plan. And the BD will come. Genesis has always embraced the newest technologies. For their '86 Wembley shows, they used HD cameras to record it, even though it was released on VHS. That's how much quality means to them. So I have no doubt that a Blu-ray version of the Rome show will happen. Sooner rather than later, I hope.
Around theatres across the world, there were screenings of the new DVD, but all we got was six or seven songs, and two hours of documentary footage. Much of the doc stuff was amazing, fasinating, funny stuff. Well worth watching.
