Yes, Austin, that is Rose of Cimarron by Poco, I think you will really like it, especially the pedal steel at the end. The guy singing lead is Paul Cotton. I don't want to speak for other TBS fans, but I don't think it is a stretch to say that in the Timmy threads, this video ranks right up near # 1 for all-time favorite Tim videos/songs - be sure to watch through 3:40 for Timothy's big finale!!!!
