Any municipality which, immediately prior to January 1, 1942, had authority as provided in "An Act in relation to the employment or maintaining of musical bands by municipalities," approved June 26, 1925, as amended, to levy an annual tax for the purpose of providing a fund for the maintenance or employment of a municipal band for musical purposes, may continue to levy the tax for that purpose under this Division 45 without submitting the question of its levy to the electors for approval, unless the electors vote to cancel the power to levy that tax. The corporate authorities may, by ordinance or resolution, cause a portion of the tax to be used to maintain and conduct programs in the performing arts providing it does not exceed .05% of the value of the taxable property within the municipality, as equalized or assessed by the Department of Revenue.
