I remember that I went to go see Gallagher at the Akron Civic Theater (that was under ownership and management of a female friend). The guy was really funny and killed it. (why doesn't good and food rhyme?) . Later, I had dinner with the lady and she said he was a real a-hole. If you've seen him, the end of his act was him smashing various things with a large mallet. The Theater was an old ornate thing that had its heyday in the 50's. They were very protective of their seats and stuff. When Gallagher got some limitations put on him before the show, he threw a fit and demanded to see the manager. When she walked up to meet him, he said "No wonder, a girl!" and demanded to see the owner. When she said she was the owner, he threw a fit. She finally said that these are the terms of the theater and they are prepared to cancel the show. He acquiesced, complaining the whole time, and just killed it.
I saw him (or his brother, I don't know which) at the Days Inn Penn State back in the late 90s
