Historically, things were pre-recorded because firstly, that is what the technology at the time allowed for, and secondly, many Hollywood adaptations of musicals have not featured actors who could handle the demands of live singing on a set. The reason the actors are singing live in this case is clearly because they are performers used to singing live, and everyone involved thought singing live would translate into better on screen performances."
Thank you, everyone keeps saying it's just a repeat of Les Miserables or a gimmick and that Hollywood totally had the musical sound nailed down in the 1950s. But the 1950s and even back to the 2000s was very limited in what technology could do. The problem with Les Miserables wasn't just live singing. First, the actors weren't particularly great singers. Don't get me wrong, they were 'good', but not quite on the level of Cynthia/Ariana/Jonathan. There ain't no Russel Crowe here. Moreover, they were encouraged to 'speak-sing' rather than belt for 'realism'. Second, it was the technological techniques they used that made everything sound reedy and weak. Wicked's soundtrack doesn't have to worry about either of those things.
Also I think it's strange that some people are suddenly praising 'dubs' from singers in old films, given how criticized that's been. Are they mad that people who can actually do what the roll calls for have been hired?
