As part of that big, 10,000 + video upload that the people behind Wolfgang's Vault, there are four live songs, professionally shot, but in B&W, from a Ranger show at the Oakland Coliseum Arena on 05/22/81. They didn't totally have their look down at this point and it is weird to see Jack with glasses and playing something other than a Hamer, but it is really cool to see the early days of the band before they expanded their name to Night Ranger.

Some of the lyrics ended up on their second album, but the music is different.
