Not a biggy. Do you recall if it was the same cruise ship or could he have been working for a different one at the time the picture was taken? Also, could it have been an older shot and maybe since it was taken, could the owner have implemented rules on attire. Do you recall if everyone else in the picture had on the Tattoo t-shirts or did they seem to be wearing what they wanted?
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.
Perhaps Steve also operated the water taxi, just a thought.
later...
