Notes from the Ron Hynes songbook, Songs of Ron Hynes Volume 1: "Godspeed was inspired by the death of Gene MacLellan. I really respected Gene. He was so quiet. He wasn't like a big industry figure. He lived in the shadow of his own fame in Rustico, Prince Edward Island, where his generosity was renowned. The song just flowed naturally and I wrote it all in about five or eight minutes. Picked up the guitar and played it right away... and I think I probably wept after. It's still perfectly intact since that moment - nothing has changed. And I always thought it was a co-write, like Gene was there sitting at my shoulder and he guided me through it."
From Wikipedia: Gene MacLellan [1938-1995] - Canadian singer-songwriter from Prince Edward Island. Among his notable compositions were Snowbird, made famous by Anne Murray, Put Your Hand In The Hand, The Call, Pages Of Time and Thorn In My Shoe. Elvis Presley, Joan Baez and Bing Crosby were among the many artists who recorded MacLellan's songs. MacLellan was born in Val-d'Or, Quebec, and grew up in Toronto, Ontario. He would eventually move to Atlantic Canada, settling in Summerside, Prince Edward Island, where he lived until his death by suicide. He won a Juno Award in 1971 for best songwriter. After his death in 1995, MacLellan was posthumously inducted into the Canadian Country Music Hall of Fame.
