Sunday in the Park with Yoko

Grace Slick wasn't the only rock fossil to emerge from her cocoon this weekend! Rock of ages!

74-year-old celebuwidow Yoko Ono turned up at a gala event in the Hamptons on Sunday -- dressed like the Mad Hatter's lunatic bride. I don't!

When it comes to insanely inappropriate ensembles -- septuagenarians do it better! Yoko loco!
