The Ultimate Collection is indeed an "ultimate collection", featuring, as it does, tracks from Petula's chart career in the UK from the 50s to the 90s, her show tunes, and some fantastic new recordings. However, the list of tracks shown here is wrong and belongs to a French release of around the same time. Ultimate was released to go with the Ultimate tour, Kaleidoscope was released in France to work alongside some concerts she was doing there and in Switzerland. Some of the tracks are the same, most are not, or are in French rather than in English. See the other entries under Ultimate Collection for correct track listing.
