<P> In his early career as a singing cowboy he composed his song Texas Plains . It was this song that Patsy Montana reworked into her million seller hit I Want to Be a Cowboy 's Sweetheart ( 1935 ) . Hamblen wrote the popular songs `` This Ole House '' ( 1954 ) ( popularized by Rosemary Clooney , among others ) and `` Open Up Your Heart ( And Let the Sunshine In ) '' ( not to be confused with the song from the Broadway musical Hair ) . Other songs include `` Hell Train '' , `` It Is No Secret ( What God Can Do ) '' ( not the contemporary Christian song of a similar name in the 1980s ) and `` Blood on Your Hands '' . Some of his post-conversion songs depict a rather wrathful version of the Gospel , sung with such good - natured high spirits that they have an ironic appeal to the non-religious . </P>
