Our hearts go out to longtime drummer of The Roots and all-around great dude Questlove, whose father Lee Andrews passed away yesterday. He was 79. Lee Andrews was the frontman for the Philadelphia-based R&B group Lee Andrews & the Hearts, a classic doo-wop group that charted on the Billboard charts all the way back in the 1950s.

Questlove, real name Ahmir-Khalib Thompson, appears nightly on “The Tonight Show Starring Jimmy Fallon” and shared a heartfelt message on Instagram. He honored the man who he considers “the greatest teacher in my life.” Questlove recalls touching moments between Lee and himself, including disagreements over his career choice, being able to provide for his father and most importantly Lee’s tenacious parenting. Read the whole thing below and make sure you have some tissues on hand.

The Greatest Teacher in my life, my dad Lee Andrews June 2nd 1936-March 16 2016. I love you. For every backstage experience. For every drum lesson. For giving me your tireless work ethic. For our father & son record binging expeditions. For our arguments over the summer I discovered #ItTakesANationOfMillions. For the look on your face when I told you "imma give this rap thing a try" (I waited til our 2nd album to have this convo btw) For the look on your face 5 years later when I told you "you don't have to work no more. For the look on your face when a year later I was like "Seriously dad, you don't have to work anymore!" For bringing my mom & my sister into my life. For the years we fell out. For the years we put it back together. But really, for the last 2 conversations we had. I understand why you were so hard on me praying I didn't succumb to a fate not meant for a teenager in west philly in the mid 80s. I didn't understand it at the time. But I appreciate it now. I hope Donn & I do you proud. #LeeAndrewsAndTheHearts
