There is a review of the Jammys at the New York Times. Here's the part about Sinead O'Connor's performance:
"The most intriguing name on the bill was that of Sinead O'Connor, the brilliant, unpredictable Irish singer and songwriter who is currently preparing to release an album of reggae covers. (She's even dressing the part: she showed up in a Marcus Garvey T-shirt and a red, yellow and green wrist band.) Unfortunately, Ms. O'Connor's performances offered only brief glimpses of what makes her best music so riveting.
She meekly sang along with Mavis Staples, the jam band Umphrey's McGee and the 1980's star Huey Lewis (this 'all-star' business can be tricky) during 'I'll Take You There.' And she reappeared later to join the reggae pioneer Burning Spear for a reggae set that never ignited. After a miscue halfway through, Ms. O'Connor became the night's only performer to utter four particularly un-jam-ish words: 'O.K., let's start again.'"
I don't see why the all-star business is tricky because of Huey Lewis. He is actually a pretty interesting guy, and he did, after all, have a lot of hits. Maybe I'm just oversensitive about it because I saw him when he toured with Stevie Ray Vaughan. It was really amazing. Plus, "Sports" is one of the most Advanced album titles ever. I'm just going to come right out and say it: I like Huey Lewis and the News.
