making a picture movie

Hey guys, i need help making a movie of pictures to show at my Great Grandmas funeral, i have most of the pics in a video (still waiting on a few family members to send me their pics).
i think i've got the pictures figured out, but i still need some help.
My aunt shot a video on her iPad of my Great Grandma singing at her 96th (?) birthday a few years ago, is there a way to rip the audio off the video to add to the picture movie?
I'm using picasa 3 to make the video.

 

My wife does this kind of stuff and says adobe premiere or adobe after effects, or apple final cut software can export the video to an audio only file.

Call a camera store, that does video stuff, or possibly look on craigslist for people advertising video service.

 

Thanks for the advice, I was able to rip the audio so the movie is almost done

 

I know the last picture isn't my great Grandma, but I didn't have time to go back through and edit the last picture out.
