After Carol (Kristen Schaal) decided to follow Phil (Will Forte) out of Tucson on The Last Man on Earth finale, the couple set off on an epic cross-country road trip.

And what's a road trip without some sweet tunes? In this sneak peak of Sunday's season premiere, Phil provides his own road trip jams, doing his best Willie Nelson impression for a rousing rendition of "On the Road Again."

The Last Man on Earth returns Sunday at 9:30/8:30c on Fox.
