Guess the 1960s song lyrics #24

1960. This song was written for the artist by a little known person who was a fan. When he met the artist, the artist told him to visit him sometime. But, the man didn't have a car. If he went, he'd have to walk. It stayed on his mind so he wrote it as a song in 15 minutes. When the man eventually made it to the city, he performed the song for the artist who loved it, made a few changes, and turned it into a hit.
