There was a Tony-Award-winning Irish-born actor with the same name who died in 2007 but the disc jockey Tom Murphy is alive and well.
I have to share a funny story. Many years ago I was driving through Glendale and saw two friends standing outside a restaurant. It was KRLA historian and author Bill Earl and Bakersfield-area DJ Jim Diamond (Gerry Whitehead). They motioned me over and invited me to join them for lunch. Tom Murphy was coming too. Tom at that time was working at KKLA. When Tom walked up to join us, Bill introduced me to Tom but didn't did not introduce Tom. Obviously I knew who Tom was. But I gasped and exclaimed, "Ohhh, you're the famous DJ?" Tom said "Yes." I said, "You used to work at KRLA and KJQI?" Tom, who was now fearful that I'm a crazed fan, gave a very hesitant "Yessss." I reached out my hand and said, "I've always wanted to meet you, Mr. Martindale!" (Referring to another KRLA/KJQI host, Wink Martindale.) Bill and Jim started laughing and Tom said, "Ooh, I know I'm gonna hate this guy." We enjoyed our lunch, though, and the next time I met him we had a good laugh over the first meeting.
