The German internet mogul and bete noir of American law enforcers, who is awaiting a deportation hearing on charges of internet piracy, has stirred up the donations imbroglio again by releasing a rap called the John Banks Song to YouTube.



The heavy-hitting track samples interviews with the ACT Party leader, including one where Paul Holmes says to Banks "you're dead meat aren't you?" before a chorus which pokes fun at another politican getting "amnesia".



Whether Banks shares Dotcom's keen sense of humour is questionable.



He has been under fire for nearly two weeks after Dotcom claimed Banks knew where his donations, which were registered as anonymous, came from.



Banks has refused to answer questions around claims suggesting he knew about the $50,000 in donations from Dotcom.



Police are investigating whether Banks knew the source of the two donations from Dotcom and a $15,000 donation from SkyCity towards his failed 2010 Auckland mayoralty campaign, which were declared as anonymous.



Electoral rules state candidates must declare the source of donations if they know the source.



Banks has said he filed his electoral returns in accordance with the Local Electoral Act 2001 and welcomed the police probe.



Prime Minister John Key has said he will strip Banks of his ministerial warrants if he is found to be lying over Dotcom's donation.
