As a taxi driver in Dundalk, Ireland, Mark Kavanagh is always up for a bit of fun with his customers. His videos of taxi conversations have gained a big following on Facebook, far beyond the small confines of Dundalk. This video shows local songwriter David Keenan thanking all those who watched and shared the first video Mark recorded of him, which gained over 50,000 views on Facebook by February 4.
