Go to Levy Sheet Music Search, put telephone in the first blank, hit the Search button, and you should get 29 songs that feature the word telephone, some of them quite well known old songs. You can also go to The Library of Congress Search, but on the right side of the first screen, be sure to click on the Limit Search to: Sheet Music first, then enter telephone on the next screen, otherwise, you'll get way too many items. That turns up 26 more, some of them duplicates of the Levy site.
