Rock and Roll Hall of Famer Chuck Berry is currently recovering from exhaustion at his home in St. Louis after falling ill at his concert at the Congress Theater in Chicago over the weekend.

Concertgoers at his Jan.1 show told The Chicago Tribune that the 84 year-old guitarist and singer/songwriter had difficulty keeping his guitar in tune and at times sat down to play at a keyboard before leaving the stage an hour into his performance."All I know is he felt faint, he felt weak, and I was told to call 911," Michael Petryshyn, the concert's promoter, told the newspaper.

An ambulance crew checked Berry's vitals and he returned to the stage to thank his loyal fans for staying. The 'Johnny B. Goode' crooner did not continue his performance, but left the concert venue in a limousine. Chicago Fire Department Fire Media Affairs spokesman Chief Joe Roccasalva revealed that Berry signed a release refusing treatment and was not taken to a hospital.

He previously performed two shows in New York the day before his Chicago gig, the Chicago Tribune noted.

Berry, a Grammy Lifetime Achievement Award Recipient, got his start in 1955 with Chess Records. Actor/rapper Mos Def portrayed Berry in the critically-acclaimed film 'Cadillac Records,' which also starred Beyonce Knowles.
