I thought it'd be nice to post some U2 / Pavarotti goodies as a tribute.
MacPhisto phones Pavarotti (Bologna, Italy, 17th July 1993)
Passengers performance of 'Miss Sarajevo' from the Pavarotti & Friends charity concert (Modena, Italy, 12th September 1995):
Bono and Pavarotti perform 'Ave Maria' at the Pavarotti & Friends concert (Modena, Italy, 27th May 2003)
[Video available on YouTube]
Bono, Pavarotti and Zucchero perform 'Miserere' at the Pavarotti & Friends concert (Modena, Italy, 27th May 2003)
[Video available on YouTube]
If anyone's interested, I wrote some background information about the charity concerts in my Song Of The Day post about the Modena performance of 'One'.
RIP, Maestro!
EDIT: Bono has now shared some thoughts here...
EDIT #2: The BBC website has an audio clip (7 minutes 46) of Bono talking and laughing about Pavarotti, it's very affectionate and sweet. Needless to say, the word "extraordinary" features a lot. ;) Go here and the link is in the top right-hand corner.
