Given this a few years ago by my aunt.
The only clue is on the back of photo which says - 3rd guy 2nd row is Topper McGlen (does not say left to right!). Also an address 23, Beech Terrace
Topper was born 1898 in Bedlington and was the son of Michael McGlen 1861 -1933
Anyone recognise any of the others? Not sure what the occasion was.
