Tune ID: Caoimhín Ó Raghallaigh slide

Found this lovely wee slide in a performance clip of Caoimhín Ó Raghallaigh (on pipes here as opposed to his more familiar fiddle). The video lists all the tunes he plays, with the exception of the slides he plays to "warm up". I was familiar with the first slide, but had not encountered the second before & quite liked it. The tune in question starts at the 3:15 mark. Thanks in advance for (perhaps) putting a name on this mystery tune. Cheers!
