Mick Jagger was on the cover of a recent AARP magazine so it only follows that a few of the "groovy" artists have re-released their great hits with new lyrics to accommodate their aging audience.
Some examples:
Herman's Hermits--"Mrs. Brown, you've Got a Lovely Walker"
The Rolling Stones--"You Can't Always Pee When You Want"
Paul Simon--"Fifty Ways to Lose Your Liver"
Carly Simon--"You're So Varicose Vein"
The Bee Gees--"How Can You Mend a Broken Hip?"
Roberta Flack--"The First Time Ever I Forgot Your Face"
Johnny Nash--"I Can't See Clearly Now"
The Temptations--"Papa's Got a Kidney Stone"
Nancy Sinatra--"These Boots Give Me Arthritis"
ABBA--"Denture Queen"
Leo Sayer--"You Make Me Feel Like Napping"
Commodores--"Once, Twice, Three Trips to the Bathroom"
Procol Harem--"A Whiter Shade of Hair"
The Beatles--"I Get By with a Little Help From Depends"
Credence Clearwater Revival--"Bad Prune a-Rising"
