I just watched Season 6 and now Season 7 on some episodes they have the full song and some they cut Making your way in the world today takes everything you've got.Taking a break from all your worries, sure would help a lot.Wouldn't you like to get away?

Did they edited it to save space on the DVD?

Nah they originally ran short.. television episodes were getting shorter and short in the late 1980s and through the 1990s. Approximatly 25 minutes in 1980, down to like 23-24 in 1990, then down to 21 minutes by the year 2000...
