A sizable chunk of George Harrison's catalog made its digital debut yesterday (Oct. 9), with the iTunes versions of his albums including exclusive bonus tracks. Harrison's catalog was the last of the four Beatles' to go digital; the band's music remains unavailable in that format.

Among the notable bonus items on the iTunes versions are an EPK video for "All Things Must Pass," an early mix of "Learning How To Love You," the previously unreleased demo "Blow Away" and an extended version of the hit "Got My Mind Set on You."

The rest of Harrison's catalog will be available digitally after the new year, according to a Parlophone Records spokesperson.

As reported last week, Harrison will be the subject of a documentary to be directed by Martin Scorsese, who has helmed similar projects in recent years about Bob Dylan and the Rolling Stones.
