There usually a debate over songs that get dropped from an album that the fans think should have been included. This would be one of the costlier ones. In 1978, Survivor was hard at work recording their debut album. As usual, some songs didn't make the final cut. This one was given to 38 Special. Their version made #1 on the charts. Survivor's version was finally released on a greatest hits compilation about 2009.
Here is the original version of Rockin Into the Night. Lead vocals by Dave Bickler and a bit of Jim Peterik (who was previously the singer for Ides of March).
