TV tonight: Music awards, 'Midwife'

The Academy of Country Music Awards/The iHeartRadio Music Awards
CBS, 8 ET/PT; TBS, TNT, and truTV, 8 ET/PT

There are so many music award shows, two of them have to share the same time slot. Assuming you feel you must choose, the bigger deal is CBS’s ACMs, hosted by Luke Bryan and Dierks Bentley. Among those expected to perform are Jason Aldean, Kenny Chesney, Eric Church, Sam Hunt, Tim McGraw, Thomas Rhett, Chris Stapleton, Carrie Underwood, Keith Urban and Florida Georgia Line — and among the highlights you can expect is a first-ever duet between special honoree Dolly Parton and Katy Perry. None of which is likely to matter to fans of The Walking Dead (9 ET/PT), which will be ending its season over on AMC.

Call the Midwife
PBS, 8 ET/PT (times may vary)

Times are changing, as this popular PBS import moves into the ‘60s. As the decade's social upheaval begins to take hold, the nuns and midwives face typhoid, lung cancer, pregnant teenagers, and babies being born with severe deformities — which, given the 1961 time period, may mean the show is about to deal with the effects of Britain’s thalidomide tragedy.

The Simpsons
Fox, 8 ET/PT

Change is also afoot at The Simpsons, where Homer is trying to find a boyfriend for a now openly gay Smithers. Alas for poor Smithers, it won't be Mr. Burns.
