Song lyrics and edit video

We have my parents 50th wedding anniversary on Saturday as as they are older we cannot get together as a family so we want to send a video of the family singing a version of Daft Pink Get lucky
We have the written the lyrics ( very basic) they need tidying up
This can be very simple - any surprise for them will be good. And we may do more professionally for their party when it can happen!
First version of lyrics attached
We need to fine tune them then we will record the grandchildren etc Singing the verses to edit with sound track
Our voices are not amazing!
All needs to be done tomorrow and Friday ready to send on Saturday
Could you do anything to help?
Thanks so much
