About a month ago I started a thread about which songs to include on a Vanagon themed mix tape.
Thanks to everyone for your great suggestions.
There were a few things that I was unable to find such as audio of a Vanagon commercial or a copy of the song Vanagon by Joe Marty. 
After a period of in depth searching and listening, here is what I came up with:
 1. Magic Bus - The Who
 2. Hell in A Bucket - Grateful Dead
 3. Scarlet Begonias - Sublime
 4. Back Udda Bus - G. Love & Special Sauce
 5. Brick House - The Commodores
 6. Double Dutch Bus - The Gap Band
 7. Catch The Bus - Mingo Fishtrap
 8. Little Blue Volkswagen - Les McCann & Joja Wendt
 9. Go VW, Go! - Johnny Cymbal
10. Ariel - Dan Friedman
11. VW Bus - The Newbees
12. Little Red Microbus - The Ditty Twisters
13. Alive & Awake - Arms of Kismet
14. Camping - Evan Olson
15. Super Collider - Fountains of Wayne
16. The Wedge - Phish
17. Blazeabeago - Keller Williams
18. Camper Made For Two - Jerry Peterson
19. Getaway Van - Current Swell
20. Vanagon - mica strong
