Green Day Singer Performs With The Replacements at Coachella
It was already an unusual set for The Replacement since frontman Paul Westerberg was forced to spend much of the time sitting on a sofa due to back problems, according to Billboard.
Armstrong appeared on the stage early during the set and helped the band perform some of their classic tracks including 'Can't Hardly Wait,' 'Color Me Impressed,' 'Alex Chilton'.
The Green Day frontman told the excited crowd during the set, "Dreams really do come true." You can see some fan filmed footage from the show here.
