Ideas for backing track in documentary

i like this song because it has a nice, calming tone and it will go with a slow paced documentary. thats the feeling i want to achieve because the song is from who is using youtube to express his talent and thats brilliant because thats the message that i am trying to portray.

This song has a very smooth melody with a bit of bass which is good because it is smoothing but at the same time nice to listen to. The only problem is i ca't find a instrumental for it and i don't want Lana's vocals in the documentary because it may get confusing between what people interviewed are saying and her lyrics. I will have to create a instrumental for it at home which may take time.

the reason i like this instrumental is because it is very jazzy and smooth which i really like because it makes the song feel vintage. More to the reason i want this instrumental is because the feel of vintage in the song emphasises the vintage look i have in my video.
