I agree about "Friend". It sounds like Fleetwood Mac at their best in the 1970's. If it were released under the name of Fleetwood Mac, even now I think it would do VERY well on the Adult Contemporary charts. It beats anything on SYW by far, in my opinion. And, it's still only my second favorite song on the album.
By the way, I just found this on eBay. I didn't even know that there was an actual CD single for "You Are".
