Thanks again, Hello Goodbye. I enjoyed those added videos of the Andrew Sisters and the D'amore Sisters. I visited the D'amore Facebook page and noted that they haven't posted anything since 2014. Also, I was surprised to learn that Bei Mir Bist Du Schon is Yiddish (To me you're beautiful). I always thought this was German but it's not, it's Yiddish. Incidentally, the song was banned by Nazi Germany because its composer was Jewish (Sholom Secunda).
Also, interesting to know that the song "catapulted the relatively unknown trio (The Andrew Sisters) to fame and became a tremendous hit for Kapp's Decca label."
Bette Midler and her sisters did their own trio version of Boogie Woogie Bugle Boy. It's very good and infectious to the max degree!
BTW: Listening to the videos on YouTube led me to listen to Funkytown by Lipps, Inc. which was in the queue. I love that song!!
