Extra audio track on my VHS

I'm trying to watch an old VHS tape, and there's a fuzzy audio track that doesn't match the movie -- it sounds like commercials and news or osmething, but hard to make out. Almost as if someone taped over it, BUT the video is intact and the original audio track is barely audible in the background. Is there any way to make this VHS watchable? I never tape TV shows or anything anyway, so I have no idea how this happened. It's only this tape - the VHS player works and sounds fine with other tapes.
