I'm 75% sure I'm going to go.. no specific date is set yet -- probably in March or April, but that's just a guess. Does anyone know any specific dates of how long it'll be there?
I did find this article..
ROCK AND ROLL HALL OF FAME AND MUSEUM ANNOUNCES MAJOR EXHIBIT FEATURING U2
FOR 2003
CLEVELAND (September 23, 2002) - The Rock and Roll Hall of Fame and Museum
announces a major exhibit featuring the Irish rock band U2. The exhibit,
which will be on the fifth floor of the Museum, is scheduled to open in
early 2003.
"U2 are one of the most important rock bands of the past two decades. They
have made brilliant music and they possess the kind of integrity and social
conscience that are often lacking in rock and roll," said James Henke, Vice
President of Exhibitions and Curatorial Affairs. "I'm delighted that they
are being so cooperative, and I think this exhibit will be a special treat
for their fans."
The Museum has recently acquired about twenty-five pieces of clothing, going
back to outfits from the 1983 War tour to costumes from their most recent
tours. The new collection also includes instruments from all four of the
band members. The Museum also has a large collection of artifacts from the
band that have been on loan to the Museum since it opened in 1995, as well
as costumes from Bono that were featured in the Rock Style exhibit in 2000.
Plans for addition artifacts are being made.
U2 formed in the late Seventies in Dublin, Ireland and in 1980 released
their major label debut, Boy, on Island Records. Since then, U2 has
catapulted to super-stardom with hits like "Pride (In the Name of Love),"
"With or Without You," "I Still Haven't Found What I'm Looking For," and,
more recently, "Walk On." Their Elevation Tour 2001 was the highest
grossing tour of the year and in 2001 Spin declared U2 the Band of the Year.
U2 is set to release the Best of 1990 - 2000 later this year.
The Rock and Roll Hall of Fame and Museum exists to educate its visitors,
fans and scholars from around the world about the history and significance
of rock and roll music. The Museum carries out this mission through its
efforts to collect, preserve, exhibit and interpret this art form.
Thanks daisybean for the info!
...thinking of Plan B....(and for the first time the "B" does not stand for Bono, but that does not mean that I am not thinking about him!
