First Day at t'Mill is a poem by Mabel F. Harrison set to music by Bernard Wrigley. He published it in 1974 on his Topic album Rough & Wrigley. He noted:

This is a poem written by Mabel F. Harrison from Yeadon, near Leeds. All her dialect poetry is written from her own experiences - she was 12 when this happened. She asked me if I would write a tune to it, and this is how it turned out.
