Query: Their worst

The Beatles were pretty much over by the preceding album (White Album) which consisted mostly of solo performances with some perfunctory overdubs. This album was their attempt to recapture their "roots" but they could not rekindle the innocence of bygone years. Only Billy Preston's keyboard work redeems this otherwise slapped-together effort. Put it this way: if this album had been a demo by some unknowns, no record company would have touched it.
