BSA Thunderbolt in Chris Daughtry Video

Free-association searching YouTube (oh what you don't occasionally do that?), I found this music video by Chris Daughtry "Start of Something Good" that stars a 1970(?) BSA Thunderbolt. I'm not sure the year, but it really is the star of the show. Once it comes in to view, you can't wait for it to have another scene. During the video a young guy possibly changes a fouled spark plug. Who knows, but in the end, it serves it's purpose - he gets the girl. Do you know the year? Post a comment and tell us.
