The boy, Sean Marshall, sings his stuff a little off key and Shelley Winters is unquestionably a great actress and plays the matriarch of the Gogans with ghoulish delight, but is clearly tone-deaf, which gives the movie a whole lot of personality. You ever notice how in musicals everyone everywhere is always a professional singer? Not in Pete's Dragon, and that's one of the things I love about this movie.

There's also another number where Jim Dale and Red Buttons gleefully sing about how they're going to cut the dragon to pieces and sell off its parts as miracle cures.

They alternate between sweet and sinister and it's a blast.

Top top it all off it's a musical and you get some real insane and decidedly non-family friendly corkers in there, like the number that kicks off the movie where the Gogans are chasing Pete through the woods and trying to coax him out of hiding by singing sweetly about how much they love and miss him, only to switch over to how badly they're going to torture him once they catch the poor kid.
