Back to the Egg is Paul McCartney's attempt to get back to rock & roll after the soft rock of London Town.
Assembling a new lineup of Wings, McCartney leads the group through a set of his most undistinguished songs, ranging from the forced arena rock of "Old Siam, Sir" to the formulaic adult contemporary pap of "Arrow Through Me" -- and those are two of the more memorable cuts on the record.
Part of the problem is the weak sound of the record and Wings' faceless performances, but the true problem is the songs, which have no spark whatsoever.
On the basis of Back to the Egg, it's no wonder that McCartney returned to solo recordings after its relative failure.
