The sisters, together with the rest of their family, dedicated the song "We Are Family" to Mr. Pressman during his wake. Yassi took to her Instagram account to share clips of the moment.
"Carry on, he said," Yassi wrote in her post. "Be strong, he said. Stay happy, he said. Always celebrate life and value the people you love, he said. Love you forever."
Mr. Pressman passed away at the age of 90 in February. Since his death, Yassi and Issa have been sharing memories of their father on social media, remembering his playful and fun-loving personality, as well as his love for music.
"Dad, I promise to keep you not just as a memory, but the energy to keep me going," Issa wrote in one of her IG posts, which featured a photo of her with her father. "It won't be easy but I know after this, I’ll be stronger. 'Til we sing, dance, and join [laughter] again."
Yassi had once described her father as her "biggest reason" in life.
