Elton John Will Headline Lollapalooza 2010 or maybe SoundGarden

April 1st (FOOLS) – Seriously though, the official Lollapalooza 2010 lineup hasn’t been announced but the organizers are giving us hints. So far the best guesses for top billing headlining acts include:

SoundGarden, Green Day, Lady Gaga, Arcade Fire, The Strokes and Phoenix.

By the way, Elton John tickets are available too.
