Which album did the Beatles record the year before Let It Be ?
With the placement of " I 'm Down " on the 1976 compilation album , " Rock ' n ' Roll Music " and the inclusion of " The Inner Light " on " Rarities " ( which was first included in the 1978 boxed set , " The Beatles Collection " , and then released as a separate British album in 1979 ) , interest in " Por Siempre Beatles " waned among collectors .
