Confirming all recent rumours, Apple has officially announced a music themed event to be held on Wednesday 9 September 2009.

The event will take place at the Yerba Buena Center for the Arts Theater in San Francisco, California, starting at 10 am Pacific Time.

The event invitation comes with the words "It’s only rock and roll, but we like it," no doubt inspired by the lead single from The Rolling Stones 1974 album "It's Only Rock 'n' Roll."

September, is traditionally the month Apple introduces new iPods, in time for the all important holiday season. Over the weekend reports suggested supplies of iPods in stores being run down in preparation for new models being announced.

"The expectations are that Apple will add video camera functionality to the iPod touch, [still] camera functionality to the nano and refresh the iTunes software," Brian Marshall, an analyst at Broadpoint AmTech said.

"That's pretty much it, although we could potentially see a refresh on the desktop too, lower prices and faster processors," Marshall added, referring to Apple's iMac systems.

Along with new iPods, rumoured to come with cameras, the event could see the launch of iTunes 9 and finally a tie-up with The Beatles.

The date also sees The Beatles copious back catalogue remastered and rereleased along with the launch of 'The Beatles: Rock Band,' video game for Xbox, PlayStation 3 and Nintendo Wii. Steve Jobs, a major fan of The Beatles, has been trying for some time to get the fab four back catalogue on iTunes.
