"By-Tor and the Snow Dog" is the fourth song from the album Fly by Night, by the Canadian band Rush.
The song is divided into 4 chapters:
- At the Tobes of Hades
- Across the Styx
- Of the Battle
- Challenge and Defiance
- 7/4 War Furor
- Hymn of Triumph
On the original, vinyl Fly by Night
album, the chimes at the end of "By-Tor and the Snow Dog" were printed into the runout groove of side one. This meant that on older turntables the chimes would play on forever, until the stylus was physically lifted from the vinyl. On the Archives
version, "By-Tor" is 28 seconds longer as these additional chimes were included.
