WATCH: This Video Of Slane By Guns N Roses Shows Just How Insane The Crowd Was

If you braved the weather at the weekend to go see legendary rockers Guns N Roses, then you'll already know how class the crowd were.

If not, then you need to watch this Instagram video posted by bassist Duff McKagan's wife Susan.

Susan was rocking out backstage at the Slane gig, and was clearly impressed with the (possibly drunken) gusto the Irish crowd were giving the band.

On her insta post she says "ABSOLUTE MADNESS!!! Most insane crowd, venue, concert EVER!"

What do you think?

Not quite as wild as Lamb of God in the Olympia in 2013, but looks nicely rowdy all the same.
