Another one of those tunes that are hardly anybody knows in the original. Including me.
The cover version of my teenage heroes Status Quo made it really famous.
Dm (Status Quo)
Straight and driving 1/8 beat (except for the intro).
Not too difficult in the melody, but hard work for your right hand thumb.
In all it comprises four parts
[ A ] intro and break
[ B ] first verses (Dm)
[ C ] bridge (key change preparation)
[ D ] last verses (Em), adding a Bm chord
By the way, I always leave out Parts C and D. Key changes and this band do not really go together.
