In his last Grammy telecast as executive producer, Ken Ehrlich has assembled at least two more "Grammy Moments" -- the special, one-of-a-kind assemblages of talent for which he is best known.

BTS, Diplo, Mason Ramsey and "surprise guests" will join Lil Nas X and Billy Ray Cyrus for "Old Town Road All-Stars." The Lil Nas X/Cyrus megahit, which logged a record-setting 19 weeks at No. 1 on the Billboard Hot 100, is nominated for record of the year.

Also, in a tribute to Ehrlich, artists associated with Ehrlich's 40-year tenure as the Grammys' producer or executive producer will gather to perform "I Sing the Body Electric" from the film and TV series Fame. The performance will feature current nominees Camila Cabello, Gary Clark Jr. and John Legend, as well as Debbie Allen, Joshua Bell, Common, Misty Copeland, Lang Lang, Cyndi Lauper, Ben Platt, and The War And Treaty.
