@ Gibb: "Alexa" sounds like "Alexer" when he sings it. And he drops his g's and final consonants. Like this:
"Well I'm on the (th pronounced as d) Downeaster Alexer, and I'm cruisin' through Block Island Sound." And "Montauk" is "Montawk". I'm no linguistic expert, but apparently dropped final consonants are common in New York accents, according to Wikipedia. And Atlantis sounds like "Atlantus".

But then, Australians (IME, at least I would) pronounce "Alexa" as "Alexer" as well.
