Conversation so far:
Did they come out with any albums during this time period?
decided at the last minute to continue as War, and use The Music Band as the title of a series of albums.
What was the name of the albums specifically?
The series originally consisted of two studio albums (The Music Band, The Music Band 2, both in 1979) and a live album (The Music Band Live, 1980).
Who was in the band during this time period?
The group lost another member when Charles Miller (saxophone) was murdered in 1980.
He had already been replaced by Pat Rizzo (ex Sly and the Family Stone) in 1979.

Question: Did someone replace Charles Miller after he died?
Self-contained rewrite: Did another saxophone player replace Charles Miller in War after Charles Miller died?
