[Historical note from Colin Bunnell: ``Ca Ira'' (``It will go'') was a popular song among the French Revolutionaries.]
This however was in 1994, and we haven't seen anything yet.
In recent (1998) interviews both Gilmour and Mason have stated that they have been doing nothing at all since 1995, no tour, no album, no nothing.
In the beginning of 1999 a rumor appeared that the band was back at David's houseboat and was recording something.
Judging from the past (AMLoR and TDB) the band has historically announced at least a year in advance that they were working on a new album. Since we haven't heard anything yet, we can safely say we won't see a new album before the new millennium.
