The introductory single from Green's second album, At Your Inconvenience, which is released today (31st), it is the first number one for both acts and records the second highest sale for a number one single this year, selling just 958 copies fewer than One Direction's What Makes You Beautiful sold on its debut five weeks ago.
Green pulled four Top 40 hits off his debut album, Alive Till I'm Dead, of which the first, Need You Tonight (an adaptation of the INXS hit) was the biggest, reaching number three.
Read All About It is the fourth straight Top 10 hit for guest vocalist Sande, who featured on Chipmunk's Diamond Ring (number six, 2009) and Wiley's Never Be Your Woman (number eight, 2010) before launching her own solo debut Heaven, which reached number two in August.
Read All About It is Green and Sande's first collaboration, and beats off fierce competition from Earthquake, the third collaboration between Labrinth and Tinie Tempah, which debuts at number two on sales of 115,530 copies - the highest sales for a number two single since Rihanna's Only Girl (In The World) was runner-up on sales of 126,612 copies behind Cheryl Cole's Promise This (157,210 sales) a year ago this week .
Labrinth & Tempah also reached number two in 2010 with Frisky and number 40 earlier this year with We Bring The Stars Out, both billed to Tinie Tempah feat. Labrinth. Earthquake is the second single from Labrinth's upcoming debut album Furtherworks, and thus billed as Labrinth feat. Tinie Tempah. The first single from the set, Let The Sun Shine, reached number three a year ago.
Unable to compete with the new arrivals, We Found Love retreats 1-3 for Rihanna feat. Calvin Harris after three weeks in pole position, but its sales are off by just 7.80% at 85,453, raising its sales-to-date to 372,268 in just 24 days. The Wanted make a much faster descent with latest single Lightning slipping to number nine (36,718 sales), a week after debuting at number two. The Rihanna/Harris single has the highest weekly sale for a number three since the very last week of 2003, when The Darkness' Christmas Time (Don't Let The Bells End) filled the position on sales of 90,922 copies.
The third and last new entry to the Top 10 is When I Was A Youngster, the second single by Rizzle Kicks. Debuting at number eight (38,611 sales), it instantly matches the peak position of their debut hit, Down With The Trumpets, which reached number eight in August, just before they assisted Olly Murs on his chart-topper, Heart Skips A Beat.
Elsewhere on the singles chart, Moves Like Jagger slips 4-5 (50,483 sales); Lego House climbs again for Ed Sheeran, moving 18-12 (29,157 sales); and American band Cobra Starship land their second Top 20 hit with You Make Me Feel... (number 16, 23,614 sales).
Overall singles sales are up 5.29% week-on-week at 3,280,199 - their highest level for 22 weeks, and 13.15% above same week 2010 sales of 2,898,963.
