Paul McCartney to be honoured by Barack Obama at White House

The ex-Beatle will appear next week, with the show being broadcast in the US over the summer.
The president and first lady are hosting the show in the East Room on June 2 for an event at which Sir Paul will receive the third Gershwin Prize for Popular Song from the Library of Congress.

Last year the prize - awarded to musicians for a lifetime of songwriting - went to Stevie Wonder.
Sir Paul hinted at the appearance when he took part in a live webcast last week in which he mentioned the White House.
He told fans: ''If there is an announcement, remember where you heard it first.''
The prize commemorates George and Ira Gershwin, the legendary American songwriting team whose extensive manuscript collections reside in the Library of Congress.
The prize is awarded to musicians whose lifetime contributions in the field of popular song exemplify the standard of excellence associated with the Gershwins.
