The remake is a film adaptation of the Broadway show that adapted the original film to stage, so there are musical numbers in it that aren't in the original. I have heard it works a lot better on stage than a movie musical, which may well be true, but as a movie I think it pales compared to the Mostel and Wilder version.

I'm really glad you liked my post! I'm always happy to wander down memory lane and talk about The Producers with people :D
