Although Curtis's involvement in the project was short-lived, Roundabout would eventually evolve into Deep Purple the following year. Chris Curtis choice of Bobby Darin's ``When I Come Home'' despite a strong band performance, was a relative chart failure by their standards, which to an extent undermined his position as song selector for the band thereafter, and some internal disagreements over musical policy/direction, that had been evident earlier when Tony Jackson left resurfaced, which probably further hindered the group's musical progression and very likely played a part in Curtis leaving in 1966.
