Ghost. I watched it on Netflix streaming. I believe Jafant is correct in that its part of a series called Classic Albums. I watched the one on The Band last night and it was equally as good. If you have trouble locating it let me know and I'll see if I can help further.
Cream: Disraeli Gears Documentary
If you've never seen this movie and loved the band, I highly recommend this. The footage and interviews are amazing. If you have Netflix streaming its on there. There's more than one Cream movie so make sure you pick this one. To be able to see Jack Bruce play Sunshine of your Love on stand up bass is priceless and Clapton with the wahwah petal when it was first invented is very cool.
