I actually saw Shucked the other day with the whole OBC - and I could definitely see a bit of vocal fatigue in "Independently Owned." (Still absolutely incredible and show-stealing, of course, but just something my parents and I noticed.) No fault of Alex, but they've kinda become the mascot of the show with their performance and that song, and I could see the strain of Tony campaigning, performing, interviewing, being flown out to do the Voice, etc. necessitating a break after Tony season is done. Luckily, their understudies are also fantastic - a friend of mine saw Rheaume Crenshaw as Lulu and loved her - so you'll be in good hands either way.
