Hello, my name is Dan Marshall, and the songs that you posted about were written by my father, who was also named Dan Marshall.
He was the fire chief in Columbus, OH back in the 70s and 80s. He passed away in 1990. I am a musician as well, you can hear some of my music at soundcloud.com/iamdanmarshall
I stumbled across this post from Google, trying to see if I could find any information about his full discography. I was only 9 when he died, so I know there are probably several songs out there that I don’t yet know about.
