Yes Don, one of their most requested songs is PP&M's "Puff the Magic Dragon" which funnily enough they never recorded in the early days.

At the last show that I saw they told a story of a chance meeting with Barry Gibb from the Bee Gees, who offered them a song he had just written. For some reason they politely refused, so the Bee Gees recorded it, and it became a huge hit. The song was "Massachusetts".

See what you think of The Seekers version.
