Conversation so far:
Where did Duke Ellington get his first start?
At first, Duke Ellington played in other ensembles, and in late 1917 formed his first group, The Duke's Serenaders (Colored Syncopators, his telephone directory advertising proclaimed)
Are there any other interesting aspects about the Duke Ellington article?
Duke Ellington was also The Duke's Serenaders's booking agent. His first play date was at the True Reformer's Hall, where he took home 75 cents.

Question: Did he have any other play dates?
