Jake Gyllenhaal Hangs With Mumford & Sons [PHOTOS]

Jake Gyllenhaal hung out with Mumford & Sons band member Winston Marshall at the New Orleans Jazz & Heritage Festival at Friday (April 29) at the Fair Grounds Race Course in New Orleans, LA.

Jake Gyllenhaal is hanging with Mumford & Sons during the The Railroad Revival Tour, which is a six-date jaunt on a string of vintage Amtrak cars traveling from Oakland, California to New Orleans. The tour, which is being filmed by director Emmett Malloy for a documentary due out this fall, is the first of its kind – an attempt to encourage creative cross-pollination among the three artists and explore alternate ways of taking a rock show on the road.

Along the way, the Railroad Revival has turned into a caravan of sorts, with more than a dozen new passengers jumping on board, including actor Jake Gyllenhaal – a friend of the Mumfords’ camp who decided to join the tour on a whim in San Pedro, without even bringing a change of clothes.

The big finale each night — with all three bands, and tour-along friend Jake Gyllenhaal thrown into the horn section — was a resounding, wild version of “This Train.”
