LEBANON — Lebanon Opera House, which returns to in-person, indoor performances next week, is requiring all patrons, staff, crew and volunteers wear a face covering at all times while inside the building.

The policy goes into effect at a concert by singer-songwriter Richard Thompson on Wednesday and will remain in place until further notice.

Joe Clifford, the opera house’s executive director, said in an email announcing the policy that attending an indoor performance comes with a degree of risk during the pandemic and that all patrons are encouraged to get vaccinated before attending a performance.
