Just take a look at Sugarcane Harris on Amazon.com and you'll see a lot of stuff.

Unfortunately, as I've seen for many artists, some of the mp3 downloads at $0.99 don't mention any credits. Tunes like "So Alone", "My Soul's on Fire", "What Comes Around Goes Around" are there for download with not mention of the fact that these were all recorded in 1972 at Seattle's Fresh Air Tavern for the Pure Food & Drug Act. No mention of song writing credits either. "My Soul's on Fire", "What Comes Around Goes Around" and "Where's My Sunshine" were all co-written by all four musicians in the PFDA. The riff from "My Soul's On Fire" was created by Harvey Mandell.
