Didgeridoo on Nasty Habits intro on Farewell
I recently found a copy of Farewell on DVD recently and while watching it today, I noticed that the "fourth" member of horn section, George McMullen, who stood well to the right of the regular horn section and who was rarely on screen, played a didgeridoo during the intro of Nasty Habits on the first song of the encore. You can see him holding it when John Avila comes on stage and just get a glimpse of it.
Once I saw it, I could clearly hear it as the drone sound under Danny singing "tell me your secrets." I had always thought it was a synth. He later switches back to trombone.
According to his website, he is "a Grammy awarded veteran trombonist and recording artist on Trombone, Bass Trombone, Flute and Didjeridoo." (https://georgemcmullen.com/index.html)
I've been listening to this album for 30 years, and just learned something new.
Just over Danny's right shoulder and above his head you can see the didgeridoo.
