I found the singing interesting. I listened to Buffalo Gals, first sung from a published score for piano and soprano, which I thought was hilarious, and then grew to like, and then an interpretation by a minstrel group, which I didn't like. The banjo player was playing on a steel-strung banjo in modern clawhammer style, and the whole thing seemed too self-conscious. I found myself prefering the 'parlour' performance, despite its absurdity. The first was authentically false, the second falsely authentic! YMMV.
