London, Sept 18 : While Sir Paul McCartney is putting up a brave front by going ahead with his Israel concert despite death threats, his family is apparently "racked with worry," according to reports.
If sources are to be believed, his children Mary, Stella, James and Heather are "very anxious" about the ex-Beatle's forthcoming gig.
"Paul's family knows he's not the type to back down but that doesn't stop them being extremely worried about him," The Daily Express quoted a family source, as saying.
The source added: "It's understood his kids would prefer him not to do the show but they also accept that their dad will do what he believes to be right and won't be scared off."
Macca has agreed to perform in Israel after dismissing death threats by militant Islamist Omar Bakri Muhammad.
The concert in Tel Aviv on September 25 will take place to mark Israel's 60th anniversary.
