NOW I know where my 70s LP record came from! Although I'm fairly certain I never saw this special, I DO remember that darn record.....I listened to it all the time as a kid. Actually, I remember the tunes as being fairly catchy, and IMMEDIATELY recognized the song mentioned by the previous poster.
IMDb mentions no network affiliation, so perhaps it aired in syndication? (NOTE: I checked my LP, and it aired on NBC.)
The Sherman Brothers rarely messed up, and I don't think this special is horrible. I'm glad I kept all of my old records....now I'm going to dig this one out, and listen to those thirty-year-old songs.
