The Beatles doing covers is a far cry from a band out there making a living by dressing up and playing the part of another band. As for Elvis barely writing any of his own material, nor did several other very prominent artists. Citing just one example, most of Johnny Cash's last recordings were all covers, that didn't take away from his originality as an artist because he had the uncanny knack of making other people's tunes his own. That goes as far back as his reading of Kris Kristofferson's "Sunday Morning Coming Down". And again, an artist doing covers is not the same as a band out there imitating another band. To each their own but it's simply not my thing. If I'm going out to see a band perform, I'm not forking my money over to see an imitation, I prefer original music.
