Just a thought/observation: Has there ever been an artist whose "new" albums have such a high proportion of archival material as Ant?
I have 25 Ant albums, and over a third are in some way collections of archival material. He was releasing archival material as early as his third album (the first PP&P)! He even has more than one type or level of archival material -- "normal" archival stuff (as on some of the PP&P collections), "really" archival stuff (the ARCHIVE COLLECTIONs), and library music.
He has sort of a unique solo career in that way, doesn't he?
