vague song question

There is a song that was played at the end of an episode of NCIS (I thing) and all I can remember is one little part - “Hello world”. It is sung by a man, a tenor, and it’s a soft/blues/ballad sort of song. That one line has been stuck in my head for DAYS and I’d like it to get out, but I don’t think it will unless I know what comes next.

Anyone have any idea what the song is??

If you can narrow down which season of NCIS, there’s a complete list of music that was used on the show here:
