The music is great, have all of the releases so far.
I've never played the laserdisc as I don't have a laserdisc player!

I have the american and british DVD releases and the british release is better imo. The video I have is pretty bad

but it's nice to watch it on the video every now and again.
I have picked up the blu ray, monday to be precise! It hasn't come yet (the 18th apparently). I got it from Amazon france and the only other place I've seen it is once on ebay for alot more money than amazon so I think there is your best bet

I'll let you know what it's like when it gets here.
