From amiga.emugaming.com/ahistory.html:
"Just 11 months after Commodore had bought the ailing Amiga Inc, they unveiled the product of that union. The Commodore Amiga (the initial name of the Amiga 1000) was unveiled at the Lincoln Centre in New York on July 23rd in a media frenzy. For the launch Commodore had hired Andy Warhol & Debbie Harry (lead singer of Blondie) to demonstrate the Amiga's graphics capabilities using Island Graphics Graphicraft. This was accompanied by a full score synthesized by Roger Powell and Mike Boom, author of Musicraft."
