Warm summer sun, shine kindly here;Warm southern wind, blow softly here;Green sod above, lie light, lie light!Good night, dear heart, good night, good night.

Where it comes in the service
At a Catholic funeral Mass the readings must come from Scripture, so a poem belongs at the vigil or in the words of remembrance. A Church of England funeral can include poetry; the Church prints poems on its own funeral planning page. In a humanist ceremony, readings of poetry and prose follow the tribute.
Add Warm Summer Sun to your booklet, typeset in full, with the order of service around it. You can see the whole booklet before paying anything.
Put Warm Summer Sun in my bookletCopyright
Warm Summer Sun is in the public domain in the United States (printed 1912 and 1916) and in the United Kingdom (Richardson died 1901; Mark Twain (Samuel Clemens), who adapted it, died 1910), so the words can be printed in a booklet without permission or a fee.
Printed here as in the source, except: Line 3: removed the dash after 'lie light!' (printed '!--' in the 1916 source).
