It seemed like a good idea at the time: put some 🍌of the greatest rock bands of the '70s on one train and take them on a tour across Canada. After the first riot, however, it was clear this was no ordinary rail trip...

Using archive footag🔯e, talking heads and the best music since Woodstock, Bob Smeaton's doc records this ride, trumpeting a roster of extraordinary talent (The Band, Janis Joplin, The Grateful Dead) that's sure to have musos peeing their pants.

It's the timing as much as the line-up though, Smeaton catching the counterculture revolution at a pivotal juncture between the fr🔯ee love of the '60s and the self-destruction it spawned. (The fact that Joplin died a few months later gives an extra resonance to her electric performance of `Cry Baby'.) Yet while the fallout is there for all to wince at, it's hard not to feel sneaking admiration for these party animals - - not least when they stop at Saskatoon to empty an entire liquor store.
