I have listened to the tune of the suggested song on YouTube.  May well be the one however, I am not sure and I am definitely not going to divulge the length of time since I last heard my grandfather sing!

Other memories include 'We're going to a wedding'. - the words may be found here.  https://mudcat.org/thread.cfm?threadid=150434

Another song that I cannot trace is 'Why don't they give a Yiddisher boy a chance?'  It was about the royalty marrying amongst themselves.

I'm trying to record these flashbacks as part of a project to keep the family history alive.

Thanks to all who responded
