For Record Store Day, which falls on April 22, Paul McCartney will offer up a special exclusive release of his cassette with his Flowers in the Dirt demos featuring Elvis Costello.

The three songs—“I Don’t Want to Confess,” “Shallow Grave” and “Mistress and Maid”—will be unearthed in their original condition just as Costello and McCartney cut them. The demos will be made available digitally only as a part of the Flowers in the Dirt reissue, due out March 24.
