Since the start of their co-headlining summer tour that began in June, Chicago and Earth, Wind & Fire have been raising money for local food banks in each concert city with their “Three Songs for Three Cans or Three Dollars” promotion.

In exchange for bringing cans of food or making donations at each venue, concert-goers have been able to download some familiar music but with a twist. The three offered songs include Chicago’s version of Earth, Wind & Fire’s chestnut “I Can’t Let You Go;” Earth, Wind & Fire’s interpretation of Chicago classic “Wishing You Were Here;” and a new, original song, “You,” penned by Earth, Wind & Fire and recorded by both groups.

For those who were unable to attend any of this summer’s concerts, the offer is on-going at, which accepts online donations.

Conceived by EWF founding member Philip Bailey, Chicago moved the notch up a bit and contacted the not-for-profit organization World Hunger Year, Inc., founded in 1975 by the late singer-songwriter Harry Chapin.

“This is a dream come true,” said Bailey in a statement. “We are honored to align with the WHY organization and help the local communities with their important work.”

Chicago’s Lee Loughnane added: “We want to invite everyone to help us do our small part to help feed America. We worked with WHY on last year’s tour. They are a great organization and we are proud to work with them again.”
