Climax Blues Band - "I Love You"

You've heard the song "I Love You" before, but had no idea who sang it, right?  The song comes from an English band called Climax Blues Band.  They originally were called Climax Chicago Blues Band, but they dropped the word Chicago under pressure from the group Chicago.  (Side note: Chicago was once called Chicago Transit Authority but dropped the Transit Authority under pressure from the Chicago Transit Authority.  God bless lawyers.)
