IIRC, the photo had part of the word TATTOO in the background behind the guy in the white shirt and two DJ's in t-shirts.
The photo is not a pix of the bridge of the Tattoo. Note that the guy in the white shirt has a mike on his headset & that neither of two guys in tee-shirts have a microphone. The guy in the tee-shirt wearing the headset is probably the one who finds &/or spins and the white shirt guy does the commentary. The headset could be for giving instructions on the next play selection on a separate channel while the music is booming?
I never implied the picture was taken on the bridge of the Tattoo.
My question is: Why is a dj wearing a captain's uniform?
