'H.E.F S.E' Campaigner, Matt Shanahan explains to Beat News what's going to be happening
"This weekend, Waterford are playing Kilkenny and we've other league matches to follow on.
We're asking hurling supporters as a start to put their hand on their heart during the playing of the National Anthem to show support for the issue.
I'd like the point out and thank the leadership shown by the regional county hurling teams who've come on board, the senior hurling panels and the managements.
We're trying to spread that message now"

Please go onto hefse.com.
You can log on there or on our Facebook page, send us a message to say you might like to give us a hand at Nowlan Park on Sunday distributing flyers, that would be most welcome."
