Glad you enjoyed Butlins, I could have sold my copy of Tribute 10 times over after playing it on Saturday!!
The song is on Defected records, I got it as a new release so it was fairly easy then, now you may have to go directly to the Defected website to purchase.
Other than that if you don't mind CD there are plenty about, the cover is a different colour but the track is on there.
You may find people offering it at silly money, keep looking you'll find it for under a tenner.
It was good to get such a great response to a record that has been played at Newark for almost a year now.
PLENTY MORE WHERE THAT CAME FROM!
Regards
