Bombay Stroll Chorus Form Analysis

Now that you've had a chance to enjoy and analyze Aki's killer instrumental "Bombay Stroll," here are the Chorus Forms (CF) he used. Mr. Aki Kumar, can you please share with everyone on your Facebook page (https://www.facebook.com/akikumar) how these CF came about? As you worked on writing this song, did you experiment with different CF's for each lick/chorus, or have you so internalized CF's now that you played the new lick at the beginning of a chorus and the CF flowed out? I assume that you worked out the first three or so choruses and then improvised by the time you reached Chorus 5? Thank you for sharing Aki.
