Thanks to Paul Watson for a photo of the original Roker chapel, known as the Bright Street chapel, (not to be confused with the one in Hull). It became the Hallgarth mission, was bombed, rebuilt and now is a Bethesda church.
See the comments below for the story of girl singing preacher Harriet Gutcher-Johnson, researched by Raymond Ella. You can see a picture and read a little more on page 305 of the 1932 Methodist Leader here. The story of the chapel opening is on page 419 of the June 21 1928 Leader here.
