Face facts, Mumford & Sons fans. Your favorite neo-folk band won’t be stopping in Madison this summer, most likely. They’ve grown too big for the likes of the Barrymore or the Orpheum — your best shot might be cramming down with the throngs at Lollapalooza this summer.

Unless you’d like to see them up close and personal — in movie form. A local fan is trying to arrange a Gathr screening of the documentary “Big Easy Express,” which chronicles a tour featuring Team Mumford along with Edward Sharpe & The Magnetic Zeroes and Old Crow Medicine Show. The tour was made by train, which became a rolling jam session as it went from town to town.

The screening is set for May 22, but the way Gathr works is that folks have to sign up ahead of time and pledge to attend. If enough people sign up, the screening happens. (It’s not unlike the Kickstarter model.) Gathr was used to bring the documentary “Girl Rising” to Madison for two sold-out showings earlier in the year.

So, if you’re interested, the link to the screening’s Gathr page is here. Hurry — they’ve got only another 15 days to make this happen, and unlike the song, Gathr won’t wait, Gathr won’t wait, for you.
