There’s No Such Thing as a free meal at John Mayer’s expense.

According to court documents, concert promoter Live Nation has been granted a temporary restraining order that prevents street vendors and other unauthorized peddlers from selling unauthorized Mayer-branded merchandise four hours before and after his New York City concert on Wednesday. The ban is effective within four miles of Madison Square Garden, where the 39-year-old is set to perform for his “The Search for Everything” tour. Official John Mayer apparel costs anything from $24 to $60, while unlicensed gear often goes for $20 or less.

U.S. district judge Vernon S. Broderick also ordered law enforcement authorities to “seize and impound” such bootlegged merchandise.  Gossip site TMZ said that the ban would be enforced by the NYPD Midtown South’s precinct, which has a dedicated task force policing the Midtown Manhattan venue.

Live Nation has filed similar requests in the past. In 2012, a court in Colorado granted the company’s request to prevent peddlers from hawking merchandise bearing the likeness of Pink Floyd singer Roger Waters. In 2011, it requested a restraining order that banned five “John Does” from selling unlicensed Motley Crew merchandise in California.

As music sales continue their decline, musicians are increasingly reliant on merchandise and concert gigs for revenue. Thanks to her “Swifties” fan club’s penchant for t-shirts with her likeness, Taylor Swift reportedly makes $17 per head from merchandise sales each time she plays a live event. According to the Future of Music coalition, sales of posters, apparel and other miscellany makes up about 2% of all musicians’ income, though that figure rises to 6% for rock stars.
