"Caravan" (Van Morrison)

It's almost hard to believe the Van Morrison who could create ebullient R&B like "Caravan" is the same curmudgeonly hermit who scowls through every live performance these days like its a chore to be around humanity.  (I kind of get it; how many times can you sing "Brown Eyed Girl" without wishing you'd never met the raven-eyed wench in the first place?)
Thing is, when Morrison is on, he's on fire.
"Caravan," which Morrison famously set ablaze during his set for The Band's 1976 farewell concert/film The Last Waltz, was inspired by Morrison's time living in Woodstock, NY, in the late 60s before the town became a household name.  
Even though his home was a half-mile from his nearest neighbor, he could clearly hear music coming from the neighbor's radio.  That experience of sharing his neighbor's music through the woods plus the bucolic, back-to-nature vibe of rural Woodstock came together to inspire his tale of red and white-painted caravans, young Gypsies dancing by the light of a campfire, and his repeated declarations to Turn it up! so that he could feel the groove coming from the radio.
The version on his near-perfect 1970 album Moondance is a rousing affair.  Morrison's voice is in top form with maximum soul, blasting out la-la-la's like his voice is part of the reed section backing him.  But the pinnacle really is the breakdown at the end of the song, where you have a whole chorus of Morrisons over that funky backbeat by session drummer Gary Mallaber.
Definitely, turn it up.
