When I'm 64?

When I’m Sixty-Four: Now that the generation which sang, ‘‘Hope I die before I get old’’ is actually getting old, can it still relate to the rock songs of its youth? Or is time to change the lyrics of such Baby Boomer classics as ‘‘I Can See for Miles’’ to ‘‘I can still see for miles, thanks to Lasik eye surgery, but I can’t focus on anything close up’’?

In an effort to better reflect the lifestyles of aging listeners, several big-name rock acts have begun updating their past hits. For example, the Beatles have released a new greatest hits collection targeted at elderly boomers. The songs include: ‘‘With a Little Help from Depends,’’ ‘‘Lucy in the Sky with Dentures,’’ ‘‘I’ve Just Seen a Face-Lift,’’ ‘‘Drive My Car (Because the DMV Revoked My License),’’ ‘‘Happiness is a Warm Bedpan,’’ ‘‘I Feel Fine (Except for Some Lower Back Pain)’’ and ‘‘Help! I’ve Fallen and I Can’t Get Up!’’

In a similar vein, Steely Dan just recorded ‘‘Rikki Don’t Lose That Walker.’’ And Lynyrd Skynyrd is reworking ‘‘Free Bird’’ into ‘‘Early Bird,’’ a live tribute to discount meals for seniors.

The Rolling Stones have also retooled several hits, according to Chris Willman of Entertainment Weekly. The new tunes include: ‘‘Angie-oplasty,’’ ‘‘Sympathy for Wilford Brimley,’’ ‘‘You Can’t Always Pee When You Want,’’ ‘‘Let’s Spend Our Remaining Time Together,’’ ‘‘It’s Only Rock ’n Roll (But I Can’t Hear It),’’ ‘‘Ex-Lax on Main Street,’’ ‘‘6 p.m. Rambler,’’ ‘‘Jumpin’ Jack Benny,’’ ‘‘Doo Doo Doo Doo Doo (Pacemaker)’’ and ‘‘Dye It Black’’ (sample lyric: ‘‘I see a gray hair and I want to dye it black’’).
