SIR Paul McCartney got a little help from a friend, when a two-year-old performed with him on stage.

The Beatles legend, 69, spotted toddler Ichiro clutching a replica of his iconic Hofner bass and dressed in a "Sgt. Pepper" outfit.

McCartney invited him up to help play "Get Back" as he kicked off his South American tour in Uruguay's capital, Montevideo.

Proud dad Pablo, who had traveled with his family from Argentina, said, "Ichiro was a fan even before he was born. This was an incredible moment. No one is bigger than Paul McCartney."

McCartney had never visited Uruguay until his gig Sunday.

His "On The Run" tour also will play in Paraguay, Colombia, Brazil and Mexico before he returns to his native UK in June to headline the queen's Diamond Jubilee concert.
