Wow, that was super-fast.

Tickets are already sold out for the Mumford & Sons’ Gentlemen of the Road Stopover festival set for Troy on Aug. 30 and 31.

The $109 tickets went on sale at 11 a.m. today and were sold out by at least 3 p.m.

We are attempting to get an exact time for the sale out.

As we were the first to tell you Tuesday, three-night camping passes for the show are $40 per person.

Those with tickets can still purchase the camping passes, a concert spokesman said via email.

It was not immediately clear how many tickets were up for grabs.

Mumford and Sons bass player Ted Dwane told us earlier this week that about 20,000 people were expected to take part if the show.

My collegue Nancy Bowman was told the festival is expected draw up to 36,000 to town for the Aug. 31 day-long event and 30,000 for music and other activities Aug. 30.

Diana Thompson, Miami County Visitor and Convention Bureau executive director, told Nancy the event is projected to have a $12.6 million economic impact on the region.

Mumford & Sons released its second album, “Babel,” in September. It was the follow-up to 2009’s Grammy-winning “Sigh No More.”

The band formed in 2007 and includes lead singer and guitarist Marcus Mumford, Ben Lovett on keyboards, accordion, drums, Winston Marshall on banjo, guitar, resonator guitar and Ted Dwane on string bass, drums, guitar.

The group’s hits include “I Will Wait,” “Little Lion Man” and “The Cave”
