The right string but the wrong yoyo

I would like to know the meaning and origin of the phrase: The right string but the wrong yoyo.

It is a song and has also been used in other areas.

Guessing: right strategy but the wrong situation? Like the song sung by Dr. John:

I been in the right place but it must have been the wrong time
I'd have said the right thing but I must have used the wrong line
I been in the right trip but I must have used the wrong car
