The Hit Factory is correct!

 Julian Lennon's debut album Valotte was recorded at several studios in America including: Muscle Shoals Sound Studios, Muscle Shoals, Alabama; Bear Tracks Recording Studio, Suffern, New York; A & R Recording Studios, New York City; Clinton Recording Studios, New York City; and The Hit Factory, New York City. Incidentally, the album was finished and mixed at The Hit Factory on the same console used by John Lennon to record "Double Fantasy." During work at The Hit Factory, Phil Ramone asked Julian, "Do you feel the ghosts?" Julian replied, "They feel good for me. The vibes feel good and I want to be here!"
