Graham Parker, like Dylan, played the lone troubadour with an acoustic guitar. Parker's self-described "Lonely-boy-on-the-road-and-in-the-bedsit" period was very low profile and collections of this material didn't show up until the 21st century. That's When You Know is such a (now out-of-print) collection of demos from 1975 and is actually quite revealing. Songs like "That's When You Know" and "I Got My Soul" show off his raw talent as a singer and as a songwriter, sans hyphen.
