When you find yourself trying to remember a show (or any works) that's on the tip of your tongue but just out of reach, come here - the collective brain of the TVTropes community can probably help. Post all the details you can remember (examples help). If you're looking for a trope, head over to Trope Finder. Have general questions about tropes? Visit Ask The Tropers!
Don't think so, but a great song nonetheless. =)
It had great emphasis on vocal harmonization, like The Turtles or Moody Blues' After You Came ( https://www.youtube.com/watch?v=T_p_knMRNnM
), just not as fast as the second one. Probably around the same tempo as Scarborough Fair and Nights in White Satin.
The moon, sunshine, wind in the hair was part of the chorus, I think.
Edited by AsuyukaPerhaps something by The Strawbs is what you're looking for? They're a folk/prog rock band from the 70s (with very strong vocals). I'm thinking the song "Starshine/Angel Wine" may fit somewhat, though it may be another one of their's too

Sounded like folk (filk) rock, with an acoustic guitar and heavy vocal melodies. Part of the lyrics mentioned sunshine, the moon, and wind through the hair. Probably 70's, I just heard this in the past couple of days. Male singer.
