The Byrds later added electric guitars and turned it into a # 1 hit back many years ago.
We've heard The Byrds' version in countless soundtracks, including the very popular "Forrest Gump" movie.
This song was also recorded by various folk artists like Judy Collins and Mary Hopkin.
I don't have a favorite version, although I love the electric guitars in The Byrds' version.
However, I love the folk and acoustic versions, too.
