This is Stephen Dean‘s delightful version of the CATALAN CAROL that links Christmas with Easter.
OCP gives you the words in their preview and will sell you the sheet music.
My backing is a bit stodgy.
There are other versions with varying texts including this one:
In fact here are some more lyrics I found:
What shall we give to the Son of Mary?
What shall we give that He will find fine?
We shall give well weighed raisins,
We shall give a basket of figs.What shall we give to the laddie of Mary?
What shall we give to the beautiful Child
Raisins and figs and nuts and olives
Raisins and figs and honey and curd.Tam-tam-tam-pa, the figs are not ripe,
Tam-tam-tam-pa, they’ll surely ripen.
If they’re not ripe on Easter,
They’ll mature on Palm Sunday.
