For the longest time (at age 10 in 1972) and for many years after, I swore that the song "Long Cool Woman in a Black Dress," actually performed by the Hollies, had been performed by the Rolling Stones! I could've SWORN this!! (Still, wouldn't it be cool to have the Stones cover this song?! Phish did, in their earliest years and just before they broke up!)
