NBC: Our next live musical is one of these two NBC’s entertainment chairman revealed the network’s next musical—sort of. Robert Greenblatt said 1957’s The Music Man will be the network’s live musical this year. Or it will be the 1975 The Wizard of Oz update The Wiz. One of those. NBC has optioned the rights to both and is considering casting options on Music Man. The network had a huge surprise hit with its first musical, The Sound of Music Live in 2013, then had a disappointment with December’s Peter Pan Live.
