I know that there's the extra verse to Tequila Sunrise, and I know of three changes to Take it Easy:

"Just find a place to make your stand..."
Changed to:
"Just find a place to take your band..."
and
"Just find a place to play your hand..."

The third change I know of in Take it Easy is:
"Looking for a lover who won't blow my cover, she's so hard to find"
Changed to:
"Looking for a lover who won't blow my cover, she's just a little hard to find"

And, of course, the changes made to Life's Been Good and Rocky Mountain Way.

Does anyone else know of any other changes to any of their songs? I'm really curious about this. I love it when bands mix things up live.
