As American TV viewers sat down to watch long-running music show The Midnight Special on March 4, 1977, they were about to watch something no television viewer had ever seen before: a group of rising stars from Seattle called Heart.
The band's debut album Dreamboat Annie had been released in August 1975 by Canadian label Mushroom – the band were based in Vancouver, BC during their early years – but it was a slow burner: it took a full year to enter the Canadian charts, and wouldn't reach the US chart until October 1976.
