Query: Al Jolson: a musical God

Al Jolson is a musical God. His minstrel image blackens his musical soul, but he displays infinite musical ability... far outstriping Sinatra, Martin, and other crooners. Jolson is alone on a musical platform with only two other performers by his side: Judy Garland and Sammy Davis Jr. This collection displays some of his musical acuity!
