Susan Jacks (née Pesklevits; 19 August 1948 – 25 April 2022) was a Canadian singer-songwriter and record producer.

[1] She began her professional career at 15 when she was asked to be a regular performer on the national Canadian television show, Music Hop.

[3] She also appeared on several other national television shows and regularly did live performances in the British Columbia and Alberta areas.

[citation needed] In 1966, 18-year-old Susan Pesklevits asked Terry Jacks to accompany her on guitar for an upcoming appearance.

They decided to add Craig McCaw on lead guitar and, although she continued to make various solo television appearances, Susan made the decision to stop performing live as a solo artist, left the "Eternal Triangle" and dedicated her time to the newly formed trio.

[1] The group began recording as "The Poppy Family featuring Susan Jacks" and had a number of hits from 1968 through the early 1970s.

Susan's brother Billy's name was chosen to replace "Buddy" and the song went on to sell nearly four million copies worldwide,[4] hitting No.

[citation needed] In 1972, the Poppy Family name was dropped and Susan and Terry worked together in the studio to record their solo albums.

[1] A few months after the transplant, Jacks was again on stage and, on 17 April 2011, performed a benefit concert for the Kidney Foundation of Canada to raise awareness of the need for organ donation.

[citation needed] Jacks died as a result of kidney disease–related infections at Surrey Memorial Hospital on 25 April 2022, at the age of 73.
