Issued on Jet Records label with :​

1. 4 prong push out with large raised ring and slightly raised small inner ring.

2. Very rare issue on almost flat solid centre with large raised or indented circle.

3. 4 prong push out that is not actually punched out !

4. Very rare white label test pressing on 4 prong push out centre with slightly raised small inner ring.

​

The Black Vinyl issue was actually the second pressing, hence the "A" demo label being on the Blue Vinyl copy.

​

It is ELO's only single to enter the UK charts twice !
