Dave, your note 1 refers to an 'eszet', a letter particular to German, I think, which can also be represented by a double s.

Title no 1. should be Ziehet fest an. The song is also called 'Song of the Volga boatmen'.

Title no 5. should be 'Abendglocken'.

I have an old album that has most of the above songs. It's great. I don't really need your scans but many thanks for doing them anyhow!
