Together with special guests the BearGrace and Tony put their spin on Aretha Franklin's 'Rough Lover' in this week's Greenroom Session.

"We had been working on making our schedules fit with the Bear's schedule for quite some time," Tony says. "So glad we did."

Grace and the Bear's Louisa "Amber" Murray take on the Queen of Soul's powerful vocals, adding some alt-country twang to the tune. Grace keeps Franklin's original punchiness in her parts, while Louisa turns the lyrics a little gentler.

"Having two female vocalists like Grace and Amber together was quite a treat," Tony says. "They have very different styles, and I feel like they complimented each other well."

And it just so happens that 'Rough Lover' is Grace's favorite Aretha song, "so that was a bonus," Tony says.

The Boot will feature the next installment of the Grace and Tony Greenroom Sessions on Oct. 1. Be sure to check back then for a new video.
