I was just looking back at some old news on the Foo's website from October 2001, and it was saying how Kerrang! had just interviewed Dave Grohl about their then new album ("One By One"). In the interview, he says that two confirmed songs on the album are 'Halo' and 'Knucklehead'.
'Halo' did get on the album, but 'Knucklehead' didnt. That was one of the tracks that Brian played on. Has any one heard it? Does anyone HAVE it?
'Have A Cigar' was actually the b-side to 'Learn To Fly', and on the 'Mission Impossible 2' soundtrack. It has Dave Grohl on drums and Taylor Hawkins on vocals, rather than the other way (in case you were bothered to know).
'Tired Of You' (with Brian) made the album, which I think is a great song, but 'Knucklehead', which also has Brian on it, was left off. But I can't find it anywhere or find any decent information on it.
