"Black and Blue" is a live video by Black Sabbath and Blue Öyster Cult ilmed during their 1980 co-headlining tour. In the video below cou can watch all 7 songs played by Black Sabbath with Ronnie James Dio on vocal.
The video was released in 1980 on VHS, with subsequent releases on laserdisc. It was due to be released on DVD in 2002, and was available for pre-order from online merchants but the release was set back several times before finally being cancelled. This was at the last minute, figuratively speaking, such that some shops in Scandinavia had put out their stock before the recall and some had illegally been sold slightly ahead of the intended release date. Most of the copies seen for sale on the internet are actually taken from the laserdisc releases: it has not been officially released on DVD, for reasons never made clear.
