Gordon Lightfoot: Gord's Gold (1975)

I'll just quote Wikipedia:

Gord's Gold is a compilation album released by Canadian singer-songwriter Gordon Lightfoot in 1975. Originally a vinyl double album, it was reissued on CD in 1987 (with one track, "Affair on Eighth Avenue", omitted to allow the collection to fit onto a single disc).

It was the first Lightfoot compilation to feature music from his 1970s Reprise Records albums, and also includes re-recordings of his 1960s United Artists hits (tracks 1-10). This served to update the earlier recordings to the same style as his later work and gives the album a level of consistency often lacking in similar compilations. Lightfoot's reasons for re-recording the United Artists tracks were explained in the liner notes as being because "he doesn't like listening to his early work".

Despite covering only the first decade of his career (and lacking one of his biggest hit singles, "The Wreck of the Edmund Fitzgerald", which was recorded the following year), Gord's Gold has remained the most commercially popular Lightfoot compilation. In 1988 Lightfoot released a second volume, Gord's Gold, Vol. 2, which also featured re-recordings of earlier hits. [source]

That says it all.
