Madonna has commented (via her representative) on the news that she is to be inducted into the 2008 Rock and Roll Hall of Fame:

'I was fortunate to have inducted my idol David Bowie a few years back, so to be included alongside him and so many other amazing artists that have come before me is an honour,'the pop icon said in a statement to The Plain Dealer, sent Friday through her publicist.
Madonna did indeed do the honours when Bowie was enshrined in 1996, although he chose not to attend the festivities.
Madonna is expected to be on hand for the Rock Hall's 23rd annual induction ceremony Monday, March 10, at New York City's Waldorf-Astoria Hotel, her publicist said.
