The Aerosmith frontman wants Trump to stop using the band's music in his presidential campaign.
Tyler joins a growing list of musicians unhappy with Donald Trump for President Inc. using their music; a list that also includes REM, Neil Young and Tom Petty.
The cease and desist order specifically relates to Aerosmith's 1973 hit "Dream On". In it, Tyler's lawyers state that, "Trump for President does not have our client’s permission to use 'Dream On' or any of our client’s other music in connection with the Campaign because it gives the false impression that he is connected with or endorses Mr. Trump’s presidential bid,
"We are unaware of any public performance license granting Trump for President the right to perform 'Dream On' in connection with the Campaign," the letter continues, "If Trump for President has any such license, please forward it to our attention immediately."
According to The Hollywood Reporter, it's the second time that the Aerosmith camp have requested that the Republican Party presidential candidate stops using the song, the first time being after an event back in August.
It comes despite the fact that Tyler and Trump have previously been seen as friends, with Tyler even attending a Republican debate in August as the tycoon's personal guest. Steven Tyler's attorney Dina LaPolt has clarified in a statement however that, "This is not a political nor personal issue with Mr. Trump. Steven works tirelessly with both Republicans and Democrats regarding copyright reform and his position has always been consistent regarding copyright and intellectual property. Simply, one must get permission from the music creators. Steven wrote 100% of 'Dream On,' and this is about the un-authorized use of his property. Steven is a registered Republican."
Trump has 24 hours to acknowledge the order, which concludes, "If Trump for President does not comply with our demands, our client will be forced to pursue any and all legal or equitable remedies which our client may have against you."
