First one is familiar but can't place it, if it comes to me I'll let you know.

3:50 is James Brown's March by Michael McGoldrick
4:40 is Noon Lassies, a Fermanagh/south Tyrone fiddle tune according to thesession.org: mind you, that's the same thesession.org that also reckons John Kirkpatrick's 'Jump At The Sun' is a traditional Irish tune ...

both the above are played as a set on Michael McGoldrick's CD Fused.
