Steven Tyler lends vocals to new single by Julian Lennon

In the past 15 years, Julian Lennon, son of former Beatle John Lennon, has released four studio albums. And he's due to release another one. He has enlisted the help of Aerosmith front man Steven Tyler for a new single he's releasing, titled "Someday"

Lennon's new album, "Everything Changes (Music from Another Room) is due out June 15. It's a pretty solid pop song. Even though Julian's last name is Lennon, like his father John, who found fame with The Beatles, he may not have found the success that comes with the Lennon name. But, over the past 30 years, he's been able to differentiate himself from the music his father may have done.
