It will be the last of a three-night run at Soldier Field that has drawn fans from all over the country and smashed attendance records at the legendary lakefront venue. More than 70,000 fans have been squeezed in each night, outdrawing not only the Bears on their home turf but previous records set by Irish rockers U2 in 2009.

Saturday night drew just under 71,000; edging out Friday's total and setting a new high mark. Sunday could be even bigger.

Chicago was seemingly an odd pick since the band's twin homes are in California -- from whence they sprung -- and the "Grateful Dead Belt" of the East Coast that stretches from Washington, DC north to the Canadian border.

But the Windy City played host to the last performance by lead singer/guitarist Jerry Garcia in the summer of 1995. He died just a few weeks later.
