Nathaniel Rateliff takes you into (what we think is) his backyard for a sing-along (we're pretty sure that's Red Rocks).

The alt artist with roots in Missouri and more recently, Colorado, shared a special video for Willie Nelson's 87th birthday, and you may not know the words to this one like you do to 'S.O.B.,' but no worries, he'll help you sing along.

According to Rolling Stone, 'The song is the latest entry in Rateliff’s Marigold Singles series, which raises money for his foundation, the Marigold Project, in support of economic and social justice organizations.'

Rateliff also reminds you to, if you go out, cover up with a mask.
