Oh. Thank you, Noreen. But why did they use a title that no-one else does? No wonder neither GUEST nor I found it there.

Actually, must admit after looking at Google index on searching 'My Old Man Said', find that 'Don't Dilly Dally' is used by some as the title, tho far more entries under 'My Old Man &c...' - see eg Wikipedia, from which the first of my above 2 posts is copied, 21 Mar 0213. The DT gives three songs called 'My Old Man', but none is this one. From the bracketed inclusion of that as alternative title as shown by Noreen above, surely it should at least be x-refd under 'My' in the DT?
