== First "British Invasion" group to tour the US? == 

 As the article mentions the DC5 appeared on Sullivan after the Beatles it may cause confusion in the minds of readers that they were the first to "tour" the US. I understand that the Beatles appearance on Sullivan and the Washington concert does not constitute a tour, but some readers may not know this information. Perhaps a qualifier as to the true nature of the tour - "extensively tour", etc. - might be appropriate to give the reader an understanding that the Beatles true extensive US tour happened later than the DC5's. Thoughts?
