What's uncommon about this common bond?

(This is a tough one!)

Find a list of songs these artists have recorded...

Then - see if you know what the uncommon bond is...

Don't know about Don Young, but Bobby Darin and Vanity Fare recorded a song called Early In The Morning, as did Graham Bond. Is he the "uncommon Bond" you were thinking of?

The common bond is -
They all recorded songs titled "Early in the Morning."

The uncommon bond is -
They were all different songs!

* The song recorded by Don Young was done by other artists under the title "She Lets Her Hair Down." I can see where the confusion comes in.
However, on the "Bang" record label for Don Young's song, it is titled "Early in the Morning." (From an old Breck commercial.)
