Together on video: Stan Getz, Guy Lafitte, Barney Wilen, Don Byas, Coleman Hawkins
The tune is not "Now is The Time" (12 bar blues). This song is a contrafact composed over Indiana chord changes. I know this song but I don't remember the title. If you know it, please leave a comment. (The tune is "Ice Freezes Red" by Fats Navarro. Thanks for the info to Turk Mauro)
