hammerman, the tune you hear was the theme tune to a sixties television comedy series called 'Mr Ed' it was about a talking horse (Mr Ed) and his owner Wilbur Post (played by Allan Young) who was the only person who could hear him talk. Mr Ed was a palomino saddlebred who according to the credits was played by himself, although he was actually voiced by Allan Dane. The theme tune was sung by Jay Livingston who also wrote the theme.
The series ended in 1966, and I can remember watching it and singing along with the theme tune - as a VERY small child... or maybe its the repeats I remember! Don't reckon Mr Ed would be able to give you any better tips than Derek Thompson though.
