The song that was played at the end of the episode when Kensi's reading her fathers diary was hard to find because there was no text to go after... Dave Kalstein - co-producer & writer of NCIS:LA - was kind enough to provide us with the info... Thanks, Dave !!
"It's a new song by Shane Brennan's very talented son, Zac Brennan. He nailed it. Perfect for those final scenes." by @davekalstein
