Hello, Dolly! - 2018 Mexican Cast

Who sings Barnaby on this CD? Luja Duhart (from the original cast) is billed alongside Jesús Zavala, as a special appearance. There are not credits for each individual track so it's hard to tell if they share the role or if only one sings on the CD. Additionally, the track listing is wrong on both the back cover and in the liner notes. This recording has the Overture as the first track. Even though "Polka" is listed as a track, it appears nowhere on the album. The packaging is a bit of a shame...
