My highschool band was "Lavender" The Riley sisters with me providing low harmonies and guitar at first, eventually gaining equal footing. Much gentler than my later band or my solo act. Less depressing, too. A lot of Ian and Silvia, PP&M, and this:
And one of my all-time favorites, the only tune done by every band I ever played in. We got up to 5-part harmony on the chorus in one incarnation, the final outrageous falsetto top part took us weeks to get right.
I noticed that Hootie and the Blowfish did a very creditable version of this, BTW.
