The Beatles star is offering two fans the chance to sit in front row seats at one of his concerts, attend the afternoon soundcheck, and meet the singer after the show.

Organisers of the auction, in aid of the Kawasaki Disease Foundation, which raises awareness of the autoimmune condition, expected to raise $25,000 with the MCCartney lot.

However, just hours before the sale's deadline on Tuesday (09Jun15), the top bid on Charitybuzz.com stood at $49,000 (£30,625).
