PORTLAND – Mumford & Sons member Ben Lovett will be pulling double duty on Saturday, playing with his bandmates on Portland’s Eastern Promenade, then strolling downtown to deejay an afterparty at Space Gallery.

Five official afterparties to follow Mumford & Sons “Gentlemen of the Road Stopover” event have been announced, with a promise of “special guests” at each.

But Lovett, a vocalist and multi-instrumentalist, was the only Mumford member specifically named as being scheduled to show up at a specific event. His afterparty will be at Space, 538 Congress St., Portland, and will begin at 8 p.m. Admission is $5.

The day-long Mumford & Sons event on the Eastern Promenade goes from noon until around 9 p.m. Saturday.

The event’s local promoter, Lauren Wayne, said it’s unclear what time Lovett will be at Space. She said the other afterparties will all have “special guests” from the Eastern Promenade event, but she wouldn’t say who they are or where they will be.

The other bands performing with Mumford & Sons on the Eastern Promenade include St. Vincent, Dawes, Maccabees, The Apache Relay, Haim, Dropkick Murphys and emcee Reggie Watts
