"Breakfast with the Beatles" was (is?) a 3 or 4 hour weekly radio program that was dedicated to their songs, their outtakes and alternate takes, other musicians covering their songs, etc. I wouldn't doubt if there were other shows like that throughout the country. Not to mention events such as Beatlefest which celebrate the Beatles. Metallica was my favorite band for several years, I had every album until St. Anger, Master of Puppets and Fade To Black are two of my favorite songs, and I still enjoy listening to them. That said, in my opinion The Beatles are hands-down the better band. Obviously, though, the two bands are quite different and likely attract quite a different fanbase.
