Thanks!!! :D :D :D

As far as I know you would find them listed by seasons, "Season 1 theme, Season 2 theme, etc.
About words - To my knowledge the M&M theme song never had lyrics. If you find lyrics for it, be sure to let me know...I'd love to hear them.

PS - I do know of one other TV show that the theme for each episode didn't have lyrics (maybe the pilot, but none of the episodes I've seen) But I found and downloaded the theme with Lorne Green singing. The show was Bonanza.
