Other mistake: When Clapton describes Cream meeting Jimi Hendrix for the first time in London, there is a period after Chas Chandler's first name that doesn't belong there. "Chas" isn't an abbreviation, and it's not located at the end of a sentence.
Factual error: On page 296, Clapton mentions rehearsals for the Cream reunion began in May 2005 and lasted almost a month. But the reunion itself was held the first week of May, so it should say rehearsals began in April.
