HOLLYWOOD, CA (Hollywood Today/AFP) 6/30/07 — Rock guitar legend and songwriter Bo Diddley, who had a heart attack in May, is back in a Florida hospital suffering more heart problems, his press agent and hospital sources said Wednesday.

Diddley, 78, is a Rock and Roll Hall of Famer and wrote such classics as “I’m a Man,” “Who Do You Love” and “Mona.” He is listed in serious condition and is coming off a heart attack about four months ago that left him with slurry speech and unable to fully identify people around him, sources close to him said at the time.

Diddley was taken to north Florida’s regional medical center after suffering dizzy spells during a regular medical checkup on Friday, said agent Susan Clary.

A hospital spokeswoman told AFP she was not at liberty to give information on private patients at the hospital, adding that no information was available on the hospital’s computer records.

Clary said Diddley had a stent implanted to aid blood flow to the heart and was in stable condition after spending the weekend in an intensive care ward.

Diddley is cited as a key transitional figure of blues into rock and roll and a pioneer of the rock and roll guitar style. His dark glasses and signature guitars became icons in the music industry after he topped the rhythm and blues charts in 1955.
