From Luke's review of "Melody Time":
Well, actualy, Donald and Zé are accompanied by the Aracuan (the crazy singing bird), not Panchito (the Mexican rooster)."Blame it on the Samba" marks, I believe, the final film appearance of Joe Carioca. Joe is accompanied by his Three Caballeros co-stars Donald Duck and Panchito, as they proceed with an existence that seems to involve Latin dancing and nothing more.
By the way, Joe Carioca also apeared in "Who Framed Roger Rabbit", but it is only a cameo. Well, I'm already being picky.
As for the DVD, I still haven't bought it (I'm waiting for the Brazilian DVD, which I hope will be unedited), but I heard great things about the picture quality.
