Bebop jazzmen Dizzy Gillespie and Benny Carter are greeting each other with
“Bell man! where have you been?”
 
Dizzy Gillespie and Benny Carter demonstrate the art of the bebop greeting as featured in Life magazine, October 11, 1948.

The bebop greeting is an esoteric jazz tradition going back to the bop dens of ancient Egypt (home of the Pharaoh of Sanders). Initiates have passed these bebop handshakes, mudras and mantras down over the centuries and they were a highly kept secret until revealed in the mid-twentieth century by unscrupulous jazzbos who clearly had no understanding of the old ways. The bebop greetings Benny and Dizzy are demonstrating in these photos are not authentic bebop ritual. If they were, both men would be subject to immediate elimination by the society of jazzassassins, a ninja-like organization originated by Rahsaan Roland Kirk and formerly known as the saxassassinators.
 

Dizzy and Benny are giving the shout “Eel-ya-da” which sounds like
bebop triplet notes.
