At least it's not as bad as 1985 where they didn't even award Best Actress in a Musical because there was only one eligible candidate and decided to not have a Best Actor in a Musical and Best Choreography award because they decided none of the candidates were worthy of being nominated (although I'm sure some of the lead roles were considered for Featured Actor/Actress):

Big River won that year beating out
Grind (a huge critical and box office flop)
, Quilters (a show only opened for 24 performances), and arguably one of the original jukebox musical
Leader of the Pack (not just a revue...although I'm sure there are older shows that mixed various songs together by one artist into a storyline before this one). There seemed to be another show called
Harrigan 'N Hart which was nominated for Best Book but only had like 4 performances and closed long before the Tonys.
I look at the 1980s and realized there was a reason why those British import musicals became such big hits. There was sort of low period of American musicals at the time even though there were some fine offerings that survived to make the American musical canon.
I sort of think the Tony performance of
Leader of the Pack is sort of charming:

Then there was the case of 1995 where only two musicals were nominated for Best Musical and for Best Actress in a musical. Best Original Score was won by
Sunset Boulevard by default as there were no other nominees.
