In the notes prior to the sheet music, it is said that an accidental note only lasts for one bar. Here in bar 3 an accidental note has been applied to the C in bar 3. In such a case why has the sharp note been added to the C in bar 4 (the note for 'broom') also? Wouldn't that auromatically be a C# as the accidental note's effect ends in the 3rd bar?
If you here the vocals track for this song, the note for 'broom' sounds like a C# also.
