On The Last Word, Matt spoke to James Flanagan about his experience of homelessness.
TodayFM's Big Busk for Focus Ireland is taking place on Friday 12th April.
Over 13,500 people are without a home in Ireland - that's the entire population of Mallow in County Cork.
Imagine not climbing into your own bed every night, not being able to cook your own dinner and trying every day to hide the fear in your eyes from your children. That's the daily reality for thousands of families.
