I may have discovered why there is currently so much interest in I've Been Everywhere, making it one of the most visited features at PopArchives.com.au.
The 1996 Johnny Cash version is being used in the US in advertisements for Choice Hotels. If you Google "choice hotels" + "i've been everywhere" you'll see that it's created some interest here and there.
I thought about emailing the sites that refer to "a Hank Snow song" (or worse, a Hank Snow "original") and telling them about Lucky Starr's 1962 original version, but maybe I'll let it rest. After all, in the States it's Hank Snow who is identified with the song, so I guess we can forgive them.
