Beltane Lyrics

Cover art for Beltane lyrics by Jethro Tull

Quite obviously, this song is about the Celtic holiday of Beltane. AKA May Day. In their tradition, May Day was the start of the new year, hence "Have you ever stood in the April wood and called the new year in?"
It's the end of April, and they are ready to call in the new year on Beltane. This song is so joyful, and come next Beltane... This song will be playing at my party :D
