Sam Sparro has once again been forced to cancel his forthcoming US tour citing visa issues. The tour was set to include recently rescheduled dates stemming from a cancellation at Santo’s Party House in New York on August 5, as well as two dates in Los Angeles on August 6 and 9. Those dates were canceled also due to visa issues and rescheduled for September. Sparro had also previously canceled an appearance at this past weekend’s V Festival.
