Rockman's cousin Jerry Lee Lewis has been a little bit of trouble, a leader for the star said.
It was expected that the 83-year-old would be better and better. Repeated in Memphis with his family next to his bed after he fell sick on Thursday, said Zach Farnum.
Lewis, known as the "Killer", began in his career in the 1950's and is renowned for visitors including Shadow's Whole Lotta Confidentiality & # 39; Goin On, Great Balls of Fire and High School.
In a statement, Farnum said it was unlikely that the Lewis concert at the New Orleans heritage and heritage festival in May would be deferred.
"The Killer looks forward to getting back to the studio quickly to record a gospel record and on the road that plays live for fans," said Farnum.
Born in Louisiana, Lewis became a renowned for the famous Sun Records, which was also an important part in the roles of Elvis Presley and Johnny Cash.
Lewis is a Grammar winner and Rock & Roll Forum Hall and is known as "a real wild rock rock".
