Steven Tyler and Juliette Barnes (Hayden Panettiere).

On last night's Season 4 premiere of Nashville, Juliette Barnes (Hayden Panettiere) was joined on stage by Aerosmith frontman Steven Tyler for a duet of Patsy Cline's "Crazy."

Meanwhile, Deacon Claybourne (Chip Esten) sang "Hymn for Her" for his comatose sister, Beverly, who was starting to come around by the end of the episode.

Elsewhere, Gunnar Scott (Sam Palladio) and Scarlett O'Connor (Clare Bowen) sang "Wake Up When It's Over," but when it came time to record the track, Scarlett recorded her part separately, attempting to deny her feelings for her ex.
