The streaming event saw Gilmour perform Cohen songs "Bird on the Wire" and "So Long, Marianne." You can watch him play through the pair in the video below, at 7:46 and 30:08, respectively.
Gilmour's choice of tracks by the iconic Canadian directly relate to Theatre for Dreamers. Samson's novel is set on the Greek island of Hydra in the '60s, where Cohen lived during that time. Naturally, he is also a character in the book.
Cohen was inspired to write "So Long, Marianne" by Marianne Ihlen, his longtime romantic partner whom he met while living on Hydra. Samson has since shared another clip of Gilmour playing along to Cohen's "Hey, That's No Way to Say Goodbye" ahead of another livestream.
Gilmour's most recent solo album was 2016's Rattle That Lock, which was followed by concert film Live at Pompeii in 2017. Last year, he auctioned off 120 guitars from his personal collection, raising nearly $30 million.
