I'm ashamed to admit that I've never heard this song before. Luther Rabb was a (relatively) well known Seattle musician in the 1970s, and apparently this song was THE song to celebrate the Sonics' championship season (which ended, coincidentally, with a victory over Washington 32 years ago today).
Anybody have access to the song that they could share with us? If not, I'll track it down on LP and find a way to upload it to the site. Seems like an important part of Sonic history, no?
