"Keep A-Knockin' (But You Can't Come In)" is a popular song that has been recorded by a variety of musicians over the years. The lyrics concern a lover at the door who will not be admitted; some versions because someone else is already there, but in most others because the knocking lover has behaved badly.
Early versions are sometimes credited to Perry Bradford and J. Mayo Williams. Variations were recorded by James "Boodle It" Wiggins in 1928, Lil Johnson in 1935, Milton Brown in 1936 and Louis Jordan in 1939. A similar lyrical theme appears in "Open the Door, Richard" from 1946, but from the viewpoint of the one knocking.
