You have created much beauty and humour through your songs, both parodies and original songs, and your arrangements of others' words and music (to mention just one example of each, Song of the Women and your 'overtures'). Since by that the world would have been a sadder and less beautiful place without you, your life has not been and is not in vain. Because you did that. Thank /you/...

(I am curious which of your songs you mention...)
