Roger the S., at work, from memory:

Hello Central get me Dr Jazz
He's got what I need I'll say he has
When I'm feeling low
And I've got the blues
He's the one that makes me put on
Both my dancing shoes

The more I gets the more I want it seems
I figure Dr Jazz in all my dreams
When I'm trouble-bound and mixed
He's the one that gets me fixed
Hello Central get me Dr jazz
