This track is incorrectly attributed to Van Morrison. The track was released by King Harvest in 1972 as a single, and then in 1973 on their album "Dancing in the Moonlight." Toploader also covered the song on their 2000 album "Onka's Big Moka."
We get it almost every night
And when that moon gets big and bright
It's supernatural delight
Everybody was dancing in the moonlight
