Ok I gotsta to defend my Bat Boy.
Another Dead Cow is integral to the plot of the show...It introduces the problem of the Cows dying in the town and by the end of the song, the townsfolk have placed the blame on Bat Boy, setting up the conflict for the rest of the show.
If there is any pointless # from Bat Boy it's Mrs Taylor's Lullabye. While hilarious and giving the Taylors some stage time it's not that necessary to the plot
Other pointless #'s in my opinion:
Crapshooter's Ballet- Guys and Dolls
You're Never Fully Dressed- Annie
Hello Dolly-Hello Dolly
All those irritating Barbershop songs in The Music Man ( i can't make it thru watching this show without wanting to shoot the Schoolboard members by the 2nd act)
Yes that's me. No, it's not a Rent homage.
