You had me barking up the wrong tree...
Unless someone has done a cover that replaces the original opening line with "Hello, Mr. DJ", I believe the song you are looking for is "Pilot of the Airwaves" by Charlie Dore.
Pilot of the Airwaves,
Here is my request,
You don't have to play it
But I hope you'll do your best.
I've been listening to your show on the radio
And you seem like a friend to me.
Play the record of your choice,
I don't mind;
I'm just happy to hear your voice saying,
'This is for the girl who didn't sign her name,
I guess she needs a dedication just the same.'
Late at night I'm still listening,
Don't waste my time chasing sleep.
My friends say I look weary,
But that's just the company I keep.
Ooo, you make the night time race.
Ooo, I don't need to see your face,
Because you're sounding good (you're sounding good)
Yeah, you're sounding good to me.
