Thomas Walker (1764-1827), remembered as a prominent English musician [see Music & Richardson, p. 59] who, along with Robert Keene, helped the Baptist minister John Rippon to compile his tunebook. Walker continued to add to Rippon's tunebook through his second, third, and fourth editions, before issuing his own supplement here. You will notice that Walker states in the title that none of the tunes herein are contained in the editions of Rippon's own tunebook.
