The List Updated.

23rd. C. Artifact, Bronislaus Janulis

1. All Along the Watchtower, Bob Dylan, Jimi Hendrix. Dylan thought this was better than his own.
2. LA Woman, Jim Morrison, The Doors.
3. Henry, John Dawson, New Riders of the Purple Sage. Baer Charlton suggested "Riders", Henry is really a driving song. 8-)
4. Ride of the Valkyries, Richard Wagner. Baer suggested Vogner, what better, though somewhat cliched, because of "Apocalypse Now".
5. Little Wing, Jimi Hendrix. I like his version, Eric Clapton has covered it, but my favorite is an instrumental cover by Stevie Ray Vaughan
6. Caruso, Lucio Dalla, Luciano Pavarotti. I could listen to him sing the phone book.
7. O Sole Mio, Eduardo Di Capua, Luciano Pavarotti.
8. Fire on the Mountain, Toy Caldwell (?), The Marshall Tucker Band.
9. Radar Love, George Kooymans/Barry Hay, Golden Earring.
10. East West, Mike Bloomfield/Nick Gravenites, Paul Butterfield Blues Band. This is a very important piece by a band that influenced the San Francisco sound, including the Grateful Dead, and their "long" versions. 
11. Dancing in the Dark, Bruce Springsteen. My cousin, Dave Westrum, suggested some other Springsteen songs, but ...
12. Candyman, Hunter/Garcia, The Grateful Dead
13. Wild Horses, Jagger/Richards, The Rolling Stones
14. Except the New Girl, Chris Isaak, Chris Isaak
15. Small Axe, Bob Marley, Bob Marley and the Wailers
16. Rebel Rouser, Duane Eddy. There are multiple versions by Duane alone.
