Positioning the British Invastion

How did Spirit stand a chance? The Beatles, The Rolling Stone, Led Zeppelin and Traffic. What mindshare could Spirit hope to gain. Finally San Francisco brands created a new niche with Airplane and The Dead. But the Brits got the mindshare that had a long lifespan with classic rock. I still enjoy Traffic. But don't own a Spirit CD, only vinyl. (Won't own an iPod.) Guess I need to pay up. :)
