According to the most recent figures, there are 7,167 homeless people in Ireland, of whom 2,407 are children.
A child became homeless every five hours in January, according to Focus Ireland.
Speaking about the issue of homelessness earlier this year, Hansard said: "It isn't just about four walls and a roof, it isn't just about a bed, it's a lot more than that.
"There's more services needed, it's a massive mental health issue and people have real needs."
There are still some tickets for the concert left from Ticketmaster outlets, at a cost of €30
