Yoko Ono and the Plastic Ono Band played recently at the Glastonbury Festival in the UK. It's a performance that's bound to make you say oh, no!

Some would argue that at 81-years-old Yoko Ono doesn't have the voice she did when she was younger. But, a lot of people would argue that she hasn't ever been good, even when John Lennon was alive.

I've heard this called post modern punk, but to me it sounds more like post-modern junk. But it's possible it fills a musical niche, somewhere.

I have to give Yoko Ono credit for one thing, she's not afraid to get up on stage and belt it out, even if it makes people question her singing ability.
