In folk music which two herbs go with parsley and sage?

The two herbs that traditionally go with parsley and sage in folk music are rosemary and thyme.

This combination is often referred to as the "four herbs" or the "fines herbes" and is commonly used in various folk songs, particularly those of English and French origin.

The song "Scarborough Fair" is perhaps the most well-known example, featuring the lines:

"Parsley, sage, rosemary and thyme

Remember me to one who lives down in the valley"

The inclusion of these herbs in songs often signifies love, remembrance, and the passing of time.
