Hymn - 'God be in my head' - can anyone find this so I can listen to it?

[KatyMac]

My uncle has picked it for my Nana's funeral & I don't know what it is or how it goes

It rings a bell

TBH it isn't what I would have chosen

Google it. Nice tune.
God be in my head, and in my understanding

May rin a bell from school. We had it as a prayer in assembly.

Well it won't be sung like that

Why couldn't he have picked Morning is Broken or something a bit more upbeat

Nana would not have liked it
