"Community" star and former "30 Rock" writer Donald Glover will return to his former show to play a younger version of Tracy Morgan's Tracy Jordan character.
A "30 Rock" representative confirms to TheWrap that Glover will guest star in the April 26 live episode. The episode features Kabletown deciding that the "30 Rock" show-within-a-show, "TGS," should be taped instead of airing live.

In addition to working as a writer and executive story editor on "30 Rock," Glover also made cameo appearances on the series.
And he does a solid Tracy Morgan impression. "30 Rock" executive producer Robert Carlock told TVLine.com, which first reported Glover's guest spot, that Glover filled in for Morgan on some of the vocals for an extended version of "Werewolf Bar Mitzvah," Tracy Jordan's novelty song. The multi-talented Glover records hip-hop under the name Childish Gambino.
Glover is also co-starring in the 2013 movie "The To-Do List," written by Maggie Carey. It also stars Carey's husband, "Saturday Night Live" star Bill Hader, as well as "Parks and Recreation" star Aubrey Plaza, Andy Samberg, Rachel Bilson, Adam Pally and Christopher Mintz-Plasse.
Glover's upcoming appearances as Childish Gambino include a performance at Lollapalooza 2012 in Chicago in August.
