Back in the day when we were students, Mr R used to play in a band so this little puzzle cache seemed appropriate and also Mrs R used to live in one of the houses overllooking the playing fields.
The coordinates are not the location of the cache itself but of a car park nearby. Please note, this car park does shut at night time so make sure you take a note of the closing time on the gates. The cache is still accessible after the car park closes, and indeed once you've worked out the coordinates you may feel there is somewhere closer to park your car 
. It's a nice area for a walk or run and we frequently take our dogs on the public fields here.
The coordinates are located here:
You will need these numbers too:
2111232
12112143
Oh and feel free to play the little ditty!
Cache contains log book only so bring a pen or pencil!
You can check your answers here: GeoChecker.com.
Good Luck.
Congratulations to Keswez on the FTF! Like the log too :)
