Re: "Hotlanta"
I can't speak to how much of a pioneer Tom Jones may have been in using "Hotlanta", but the first time I ever heard the phrase was on my dad's .38 Special album (Rock & Roll Strategy) which has a song called "Hotlanta", but the Internet tells me that the Allman Brothers Band had a song with the same name as early as 1971.
Searching Google Books the term really explodes in the 1990s, but prior to that it seems like it was used a lot by CB Radio aficionados in the 1970s (despite not being in "Convoy") and then was the name of an annual gay festival in Atlanta in the 1980s through the 21st century.
The *earliest* reference I could find to Hotlanta was in a 1949 journal of tree science.
How Tom Jones discovered the term remains an intriguing mystery.
Also really surprised that Jimmy doesn't own the same late 1980s .38 Special albums my Dad does, given the massive overlap in their record collections.
