I'm part of a team at the University of Sheffield, led by Dr Chris
Stride. We've published a number of academic papers and magazine
articles relating to football history, on subjects such as statues and
replica shirts (see, for example sportingstatues.com, annd:Shirt tales: how adults adopted the replica football kit).

Our current project is investigating the music that football teams have
run or walked out of the tunnel to over the years.

Having been in contact with a number of historically minded Evertonians, I realise 'Z Cars' has been used at Goodison Park since around the spring of 1962, and is to proudly in use today.

However, I wondered if any fans knew of any instances in which Z Cars had been replaced by another song or version? If so, what was the response among fans at the time?

I should also add that we are not interested in goal music, or a song
that is played at the final whistle, but just the song that is on the
tannoy system as the players enter the field.

If you think someone else may be able to help, or you have any
questions, please let us know!  We would be very happy to discuss the
project.

Thanks for your time,

Joe Headland
