GREATEST HITS
ABC, 9:00 p.m. ET
SERIES PREMIERE: ABC is trying a lot of old tricks this summer – game and quiz shows, mostly – and here’s another one, a musical variety show that invites both current acts and oldies to perform numbers from a particular five-year era. It starts with the 1980s, so these are relatively newer oldies, but time goes on. Hosted by Arsenio Hall, who’s 60, and rising country star Kelsea Ballerini, who’s 22, this new six-part series, which is arriving without previews, may be a lot of fun. It’s executive produced by long-time Grammys producer Ken Ehrlich, whose tastes in music, and in pairing musicians from different eras and genres, has been a delightful Grammy staple for decades now.
