I also helped set up the stage for a concert on a ship on a military base (the stage work was probably the weirdest work I ever had to do in the military, but I will probably post the details on a different thread).
Another concert was on my ship. Both of those concerts had something like 10 different groups of performers, including Jeff Foxworthy and "The New Miami Sound Machine" which is 3 girls mentored by Gloria Estefan. This concert was in Fort Lauderdale, FL and was nationally televised.
The movie "Tears of the Sun" (Bruce Willis) was also filmed on my ship, and somone I worked with was an extra in the movie. He made friends with the cameraman, and while we were on deployment the cameraman e-mailed him photos of Pamela Anderson during the making of his next movie (Baywatch Hawaii).
We also had a very strange USO show, while we were out at sea, that consisted of John Elway, Robin Williams and a female porn star (not sure her name and didn't know who she was before that but she was advertised as a big-name porn star). I found out the Robin Williams stand-up comedy was uploaded to youtube in 3 parts, so maybe I will post those on another thread.
