It's not well known that Marv Levy loves fight songs. One time, when the Bills faced a big game, he promised that he'd write one for the team if they won. Marv kept his part of the bargain. He then sang it on his show on the Empire Sports Network.
Here's an eight-second clip; there must be a longer one somewhere:
I went out to Colorado right after this and visited Glenn Locke. When the full clip was teased, I told him he had to watch ... but he showed limited interest. Then it came on.
Once Glenn stopped laughing, he said, "You didn't tell me this was the funniest moment in television history." We just have to find the long version for YouTube.
