Lyrics to 'I Promise You'

I am looking for the lyrics to the song "I Promise You" from the move "Here Comes the Waves" starring Bing Crosby and others. While I am unfamiliar with the movie and song, I want to include the lyrics in a tribute to my Grandfather. He passed away two weeks ago and was faithfully married to my Grandmother for almost 70 years. If anyone has the words to this song, I would love to have them.
Thank you
Katie in So. Cal
