My friend Mrs. Lev has another puzzler for us. She's wondering if there's anything more to this song.

Hush-ta-ra-ra-ray
Hush-ta-ra-ra-rah
Times is gettin' hard
A dollar a day is all they pay
For work on the boulevard.

We do have one song, Last Winter Was a Hard One (Rise Up Mrs. Reilly), that has the phrase "work on the boulevard." No connection I can see, though.
