A wide-ranging group of Canadian performers headlined the closing ceremonies of the 2010 Vancouver Olympic Games, including a surprise appearance by Neil Young, as well as songs from the likes of Michael Buble and Avril Lavigne.

The performers had been kept as a closely guarded secret until the show, which followed the conclusion of the games, but some names, including Canadian rockers Nickelback, and hip-hop act k-os, had leaked out prior to the show at BC Place in Vancouver last night (Feb. 28).

The Rock and Roll Hall of Fame and Museum in Cleveland has fascinating relics like Michael Jackson's "Thriller" mask. Soon it'll have space to showcase its interesting but less flashy artifacts.

The museum will open its library and archives later this year in a $12 million high-tech building it shares with Cuyahoga Community College's creative arts programs.

Jim Morrison's first poem will be there as well as and letters from the Grateful Dead, Whitney Houston, Patti Smith and others. There will also be old audio and video recordings, contracts, album covers, posters and scrap books.

Student and professional singer Tracy Marie hopes the museum-college collaboration will encourage young artists to aspire to have their campus studio work enshrined in the archive.

Jason Derulo's "In My Head" (Warner Bros.) became the American singer's first U.K. No. 1 single, as Lady Gaga's "The Fame" (Interscope/Universal) started a new stint atop the album chart, and the top ten welcomed new hit albums by Marina and the Diamonds, the Courteeners and Johnny Cash.

"In My Head," which holds at No. 9 on this week's Billboard Hot 100, follows up Derulo's U.S. No. 1 "Whatcha Say," which reached No. 3 in the U.K. and was top ten in several other European countries.

The new single held Florence & the Machine and Dizzee Rascal's "mash-up" "You Got The Dirtee Love" (Dirtee Stank/Universal Island) at No. 2, where it debuted last week after the two artists performed it together at the BRIT Awards Feb. 16. Rihanna's "Rude Boy" (Def Jam/Universal) climbed 6-3.
