I can't imagine Elvis at 75 years old -- that's almost as old as my dad! Indeed, they're only 8 months apart. Elvis died when he was 42 -- on my dad's 42nd birthday. I was with my dad that day and learned of Elvis's death -- it was one of those things, one of those days, the circumstances seared into my brain for life!
Anyway, I'm not a must-visit-Graceland-someday Elvis fan, but I've been a fan ever since I saw the 1968 Comeback Special. That's my kind of show -- intimate, easy-going, funny -- leather. I'm sure that an Elvis release was among my first Christmas album purchases (and, yes, it was an album... as in vinyl... LP record), along with Johnny Mathis and Barbra Streisand, part of the indispensible chorus that makes my Christmas.
Note: I prefer the original, black-and-white version of Jailhouse Rock, but it was squishy. It's one thing to be 75, another to be squished.
