Canada Day celebrations at the Confluence in Calgary feature multi-Juno award winning Canadian rockers the Sam Roberts band on the main stage at 9:45 p.m. Sam Roberts joins Sarah to talk "Seven Degrees of Sam Roberts" plus the role of songwriters right now in documenting Canada's newfound strength and independence at a critical time in history. And a very Canadian humble nod when you understand you're sometimes viewed as the opening act to fireworks.
