Irish Eyes Are Smiling

Hi, There, I recently had a new friend enter my life that I just treasure. He is in quite ill health and likely won't be around too much longer. His brother, also aging and in poor health, sang on the original movie (When Irish Eyes are Smiling). I am not certain what the details are regarding this, only that he sang. Since I heard my friends story, I have been working feverishly to obtain a copy of the movie I could give him to enjoy his brother, who he doesn't get to see too often as they are separated geographically and are both ill and elderly. He has so much love for his brother and I see it come shining through every time I talk with him. I would love nothing more than to give him a copy of this movie that he could enjoy and possibly share with his brother. Does anyone know if it is out on DVD, if so, where the heck I might find it. I've searched the web over, to no avail. I would appreciate anything anyone might be able to offer. Thanks in advance for your help.
