John Lennon's sons JULIAN and SEAN look set to reignite their long-running feud with a new chart battle - after both announcing plans to release albums this year (06). Julian, who was born during the late beatle's first marriage to CYNTHIA LENNON, and SEAN, whose mother is John's widow Yoko Ono, sparked their first public spat eight years ago when they controversially released CDs on the same day. And Sean, 30, refuses to deny the possibility of another clash with his 43-year-old half-brother: "I'm just finishing the cover design. Then it's up to the record label when it comes out." A source tells British newspaper the Daily Express, "The fact that both brothers are finally bringing out new albums is interesting in itself. "Their release dates will be crucial. It seems Sean's album is further down the line, but this doesn't rule out a battle of the brothers - whether either of them like it or not."
