Don't know why, but he was always a favorite. Some great songs, some great guitar.
He was always a favorite of mine too. He was an immense talent. Being a big fan of Jimmy Webb too, my favorite songs by Glen were By The Time I Get to Phoenix, Galveston, and of course the sublime Wichita Lineman.
His (much more famous) version of the great John Hartford's "Gentle On My Mind" was probably responsible for Hartford's becoming well-known, for which many owe Campbell a debt of gratitude. And wow, he was still alive!?
