Are there any songs or bands from the 60s/70s that qualify as both Folk and "Bubblegum Rock"?

As a child, I enjoyed both genres—both of which are virtually extinct today. One of the bands I enjoyed in the ‘70s was Steel Eye Span. Seems like there was a group called Thor’s Hammer (or Vulcan’s Hammer or something)— anyhow, I’m on a nostalgia binge again. Can anyone give any examples of Folk/Folk-Pop and Bubblegum Pop Rock crossovers?

You don’t need to be a serious music expert to answer this—just recall the sweeter harmonies of a time when love was the answer to everything, and a greater mystery or “something more” was just beyond the veil —just beyond our reach but we were almost there.

Usually such songs were upbeat, harmonious, and something we could sing to.
