Ace in the Hole
They're still considered a OHW. "Darkness Darkness" only reached #86. To be considered a OHW, the artist must have only one chart in the Top-40, irregardless of any other Hot-100 songs. As, "Get Together" reached #5, it's a no-brainer.
The funny thing about "Get Together" is it only got to #5 after a radio public service announcement used their song in 1969. Originally it only peaked at #62 in 1967, so I suppose you could say the Youngbloods were nearly a "no hit wonder".
Not sure if anyone has mentioned "Next Plane To London" by "The Rose Garden", peaking at #17. Think it was the only hit they had, though they have some other good songs on their album.
