I Don't Feel Like Dancin' was the top UK single for the fourth time, while the New York group's album Ta-Dah also held on at number one.

Lil' Chris, Evanescence, the Pussycat Dolls and the cast of High School Musical moved into the singles top 10.
Checkin' it Out by Lil' Chris climbed from 19 to three, and there was also a big jump for Evanescence.
The rock group's song Call Me When You're Sober was number four, after being at 32 last week.
Justin Timberlake completed the top five, falling two places to five with Sexyback.
And the highest new entry in the top 40 was Breaking Free, from Disney's High School Musical, at number nine.
On the album chart, there was only one new entry in the top 20 - Walk With Me, by Jamelia, at 20.
She was one of the nominees at last week's Music of Black Origin (Mobo) awards in London.
The Fratellis stayed at number two with Costello Music, while Razorlight's self-titled release moved up four places to three.
