Also on the show: Black Eyed Peas doing “Three is a Magic Number,” Julianne Hough singing “Interplanet Janet,” Ne-Yo crooning “Verb: That’s What’s Happening” and Raven Simone teaming with Kaleidoscope Penn on “Interjections.” Ryan Seacrest again hosts this fifth installation in ABC’s “Singalong” series.
