There are a LOT of deserving songs in there - some I haven't heard (or heard of) - so can't comment on those; but i'll take your sage opinions and avoid them like the plague.

There are some though that i confess to enjoying on occasion ("It's Hard to be Humble" is one - I love playing this for schoolkids and watching then try to work out whether I'm serious or not: a 'cleaned up' version for them)

HOWVER! I'd have to go one step further than the person who mentioned "Grandma's Feather Bed"
To be perfectly honest, just about ANYTHING (in fact, probably EVERYTHING) sung / recorded by John Denver makes my hair hurt - and that's no mean feat considering how little of that I have!!!!!

I think the best John Denver comment I've heard was in the film "Behind Enemy Lines" where Owen Wilson's character is bemoaning the loss of so many great performers to (quote) 'shitty pilots'- he names Lynyrd Skynyrd, Richie Valens, the Big BoppaBuddy Holly etc and his pilot suggests wryly "John Denver?" to which he replies "Well let's not get carried away!"
