This is in fact Swingers project with guest vocals by various artists. It's little confusing since cover is designed to suggest it is some kind of various artists compilation - Swingers play on all records, and artists listed on the inlay are featuring artists. It can bee seen on tracks 5 & 12 - there is no artist listed (name Swingers is omitted from labeling all tracks). Booklet notes & credits are clearly written as it is Swingers album.
