According to rollingstone.com, Pras does an interpretation of "I Still Haven't Found What I'm Looking For":
"I got Bono's cell number, and I called and asked him," Pras recounts on the San Fernando Valley set of the song's video shoot. "He said, 'Really, my biggest record of all time?' I sent him the idea, he played it for the rest of the band, and they loved it. Bono called me back and said, 'Listen, I've never cleared a record for anyone, but I'm a fan of the Fugees and a fan of you. If this record can help you, go ahead and take it.'"
Somewhere, Negativland is smiling (sarcastically). Oh, and Advanced artists always allow their songs to be covered by hip-hop artists.
