It takes Dolly awhile to warm up to the lyrics past "whisper singing/coo-ing" for her first few parts. Reba owns the song and Dolly is just along for the paycheck/possibly Grammy nom for best Country Duet/Collab.
All in all, though, it seems like a half-assed catfight at the assisted living facility over one of the young CNAs who couldn't care less about either of these old bitties. And I'm a Dolly fan, but she sounds weak and feeble in this one. Also, notice how Reba swigs back her drink, but Dolly only faux-sips her white wine. Tips to staying stick thin at age 75!
