Not many people know but John Legend wasn’t only here for a concert, which was successfully held last September 26 at The Araneta Coliseum.

He had another agenda.

A day before his much-awaited concert, the singer-songwriter went to a studio in Mandaluyong to record a song which will be part of the soundtrack of the sensational movie adaptation of the bestselling novel by E. L. James, “Fifty Shades of Grey.

Boyet Carlos Aquino, a recording engineer at Spryta Productions, Inc., exclusively told Yahoo Philippines that the promoters of the show brought Legend to the studio.

He recorded a song which I guess is for the upcoming movie ‘Fifty Shades of Grey’ because that’s the name of the pro tools project file that came from him,” Aquino told Yahoo.

He is one of the nicest guys I’ve worked with. He really knows his way in the studio,” Aquino said of Legend.
