Bajan quartet Cover Drive went straight to No. 1 on the U.K. singles chart yesterday (Jan. 29) with "Twilight" (Global Talent/Universal). Ed Sheeran's hit debut album "+" (Asylum/Warner Music) moved back 2-1 for its third separate stint at the summit.

Cover Drive reached No. 9 last September with their first British hit "Lick Ya Down" which will, like the new chart-topper, be on the group's debut album "Bajan Style." Selling 76,000 copies, "Twilight" took over at No. 1 from Jessie J's "Domino" (Lava/Universal Island), which fell to No. 3, although her album "Who You Are" jumped 10-7. "Titanium" (Positiva/Virgin/EMI) by David Guetta featuring Sia climbed 3-2 (66,000) and Australian artist Sia now has the distinction of simultaneous top five guest appearances, with "Wild Ones" (Atlantic/Warner Music), the Flo Rida single on which she features, debuting at No. 5. Flo Rida himself has two current top ten hits, with his former No. 1 "Good Feeling."

Sia isn't the only artist making this a proud week for Australian-nurtured talent on the U.K. charts. "Somebody That I Used To Know" (Universal Island) by Gotye featuring Kimbra continued its progress with a 21-7 climb. Gotye was born in Bruges, Belgium, but his parents moved to Melbourne when he was two. He has gone on to win five ARIA Awards. "Somebody..." is his first U.K. chart entry.

Also moving into the new top ten were Kelly Clarkson's "Stronger" (RCA/Sony Music Entertainment), 11-8, and "International Love" (J/Sony Music Entertainment) by Pitbull featuring Chris Brown, 13-10.

Sheeran's album now has U.K. sales of just under 881,000, according to the Official Charts Company, but only needed to shift 20,000 new units to regain the peak. Coldplay's "Mylo Xyloto" (Parlophone/EMI) climbed again, 3-2, as Adele's "21" (XL Recordings) moved into its second chart year by falling 1-3. Bruno Mars moved back 5-4 with "Doo-Wops & Hooligans" (Elektra/Warner Music) and Rizzle Kicks' "Stereo Typical" (Universal Island) improved 9-5.

There was a notable chart comeback for Chris Isaak, whose album combining remakes of Sun Records artists' hits and new material, "Beyond The Sun" (Rhino/Warner Music), debuted at No. 6. That's the first time he's even been in the top 40 of the U.K. survey since "Forever Blue" reached No. 27 in 1995, and his highest ranking since he made his album chart debut with "Wicked Game," which climbed as high as No. 3 in 1991. "Noel Gallagher's High Flying Birds" (Sour Mash) moved 12-9.

The compilation chart saw a new leader, as the nine-week reign of "Now! That's What I Call Music 80" (EMI TV/Universal Music TV) was ended by Sony Music's "Be My Baby," a new collection of 1960s material by female groups and soloists, from the Ronettes and the Supremes to Peggy Lee and Nina Simone.
