If you want some background entertainment for your New Year’s Eve party, or just some foreground entertainment to slip nicely from one year to the next, here’s a strong option. TCM is presenting a triple feature of all three editions of That’s Entertainment, which are nothing-but-highlights compilations from the history of MGM musicals. The first one came out in 1974, and gathered as co-hosts an absurdly talented group of entertainers – all of whom are represented in the clips as well, starting with Fred Astaire and Gene Kelly.
