question: What is the last name of the person who helped premiere the cologne at the after-party for his first Garland tribute?
context: Part of the success of the tribute concerts can be attributed to the amount of press attention received and the eagerness of other artists to participate in the event. As written by Gaby Wood of The Guardian, Wainwright "sparkled on the cover of Time Out New York" and was "adored in the pages of The New York Times" following the Carnegie Hall shows. In fashion designer Marc Jacobs' menswear boutique in Greenwich Village, "virtually nothing was for sale except T-shirts advertising the show" (the bright orange shirts contained the text "RUFUS RUFUS RUFUS" and "world's greatest entertainer", mimicking promotional material used for Garland 45 years earlier). Film director Sam Mendes planned to create a documentary about Wainwright's re-creation and the work leading up to it, though the project fell through. Dutch designers Viktor & Rolf outfitted Wainwright and his family members for the concerts. To return the favor Wainwright wrote the song "Ode to Antidote" and allowed its use in the promotion of the design duo's cologne, "Antidote". He also helped premiere the cologne at the after-party for his first Garland tribute and later performed "Over the Rainbow" at the premiere of their Spring 2007 fashion line. Wainwright wore clothing by Tom Ford at the Hollywood Bowl concert. To promote the album, Wainwright's website linked to an online store where fans could purchase merchandise, including several shirt designs, concert posters, programs and other collectibles. Like the shirts sold by Marc Jacobs, much of the promotional material mimicked posters used for Garland's concert years before.
  Celebrities attending the Carnegie Hall shows included Justin Bond ("Kiki" of Kiki and Herb), Patricia Field, Gina Gershon, Joel Grey, Marc Jacobs, Michael Kors, Tony Kushner, Ann Magnuson, Sarah Jessica Parker, Kate Pierson, Fred Schneider, the Proenza Schouler boys, Chloë Sevigny, John Waters and Viktor & Rolf. Famous faces turned out at the concerts in Europe as well, including Julian Barratt, Keane frontman Tom Chaplin, Julia Davis, David Furnish, Mark Gatiss, Richard E. Grant, Jeremy Irons, Lulu, Paul Morley, Siân Phillips, Imogen Stubbs and Teddy Thompson. Celebrities at the Hollywood Bowl show included Jamie Lee Curtis, Jimmy Fallon, Jake Gyllenhaal, Debbie Reynolds and Rod Stewart.
