After some speculation sparked last night when frontman Jeremy McKinnon tweeted a picture while flying over Chicago, A Day To Remember have now confirmed they are playing a surprise set at Warped Tour today at Midwest Bank Amphitheatre in Tinley Park, IL.

As APTV Los Angeles correspondent Nick Major who is on site reported to us, “People are freaking out over it!” Understandably so. The last time the band appeard on Warped was in 2011.

ADTR's surprise appearance marks the second of two massive special guest appearances on this year's run.
