Yes, Adelaide Hall was American-born but was a UK-based entertainer and jazz singer.
One of my favorite Jazz musicians is Adelaide Hall.
I really love jazz as a musical genre.  Do you like jazz? I'm not but do you like free jazz? It got made around the 1950s to the 60s. I have never heard of free jazz.  What are some of its most popular artists? I'm unaware of any and another about free jazz is that defining it is difficult as it was never a distinct genre. I see, my favorite jazz musician was Duke Ellington and Adelaide Hall, ever hear of them?
