RCA NashvilleWe already knew that Maren MorrisLittle Big Town, and Kacey Musgraves would be performing on Sunday’s Grammys, but now we have a better idea of what exactly they’ll be doing: Maren, LBT and Kacey will all take part in a tribute to Dolly Parton, who’s being honored as this year’s MusiCares Person of the Year.

Katy Perry — who previously sang with Dolly on the 2016 Academy of Country Music Awards — will do one of the icon’s classic hits as well.

Dolly herself will also perform a new song from her latest album: the soundtrack for the Netflix movie Dumplin’.

You can tune in for the 61st Annual Grammy Awards Sunday at 8 p.m. ET on CBS. Dan + Shay and Kacey will have their own performance slots on the show as well.
