I think the best one is Green Acres. I also like Mr. Ed, Peter Gunn, The Brady Bunch, All in the Family, Cheers, Hawaii Five-O, Bonanza and Dick Van Dyke. By the way: If you know the lyrics to any of them that only had music on the show, post them.
Here are the lyrics for The Dick Van Dyke Show.
So you think that you got trouble, well trouble's a bubble
So tell old mister trouble to get lost.
Why not hold your head up high and stop crying,
Start trying and don't forget to keep your fingers crossed.
When you find the joy of living is loving and giving,
You'll be there when the winning dice are tossed.
A smile is just a frown that's turned upside down,
So smile and that frown'll get lost.
And don't forget to keep your fingers crossed.
