LET ME CALL YOU SWEETHEART - Ukulele video tutorial by UKULELE MIKE LYNCH

I had originally posted this video lesson on You Tube and although it was written in 1910 and clearly a public domain song, it got flagged by You Tube as copyright infringement. I'm left confused by You Tube as to what they are asking of us. I posted this on VIMEO and I ask your patience as I know many are having poblems with VIMEO relative to android devices etc.

You have a load of Beatles stuff on Youtube. Do they not flag that as copyright?
