On Monday (Jan. 28), Eric Clapton announced that he is putting out a new album, 'Old Sock,' on March 12. Apart from the track listing, not too much other information has been available about the project. However, on Wednesday (Jan. 30) Clapton revealed the many guest stars who will appear on the record.

The quality of cameos should take the sting out of seeing the cell-phone-camera-vacation-self-portait that is being used for the cover photo. Digital Spy is reporting that Clapton's old partner in Blind Faith, Steve Winwood, will provide his signature soulful organ playing to 'Still Got the Blues.' Paul McCartney, on whose 'Kisses on the Bottom' Clapton played, contributes bass and vocals to 'All of Me.'

Two other musicians of note lend their talents to 'Old Sock.' JJ Cale -- who wrote Clapton's hits 'After Midnight' and 'Cocaine' -- plays guitar and sings background vocals on 'Angel,' while soul legend Chaka Khan ('I'm Every Woman,' 'Tell Me Something Good') sings on 'Get on Over.' Bringing it full circle, Khan also sang on Winwood's 1986 smash 'Higher Love.'

'Old Sock' will be released on Clapton's own Bushbranch Records label. It contains ten covers and two originals, 'Every Little' and 'Gotta Get Over.' The legendary guitarist will play a month of shows beginning March 14, culminating at the two-day Crossroads Guitar Festival at New York's Madison Square Garden on April 12 and 13.
