MJ's 'This Is It' comeback concert leaked online

London (ANI): The contract for late King of Pop Michael Jackson"s 'This Is It" comeback concert has been leaked online, with documents confirming the tragic star had no “known medical problems" which would have jeopardised the London shows.

The contract with tour promoters AEG, obtained by RadarOnline, stated the star had no “known health conditions, injuries or ailments that would reasonably be expected to interfere with Artist"s first class performance at each of the shows during the term," reports the Daily Express.

The documents also reveal that singer did in fact agree to play more than the original 10 concerts, but stipulated that he would perform no more than “3.5 times" during a seven-day period. The papers also dismiss rumours that Jackson was too frail to perform his full set.

Many internet gossips speculated he was only contracted to appear on stage for a small portion of each gig, but the contract states he was obliged to perform for at least 80 minutes at each show. Jackson signed the documents on behalf of his company, The Michael Jackson Company LLC, and as the artist, Michael Jackson, while AEG Live CEO Brandon Phillips also signed the contract.
