Wet weather did not dampen the spirits of nearly 400 singers who gave Chesterfield town centre its greatest free show for many years.
Twelve choirs from around Chesterfield, South Yorkshire and Nottinghamshire produced six hours of continuous vocal entertainment throughout the town centre.
They performed in New Square, Vicar Lane arena, Chesterfield Library foyer and the Pavements shopping area.
The singing started with the Carolare Choir in the Pavements and the Co-operative Choir in the library.Holmebrook Valley Singers followed on The Pavements with Chesterfield Philharmonic Choir in the library.
Aurora, the ladies acapella choir, opened the proceedings in Vicar Lane with Chesterfield male voice choir continuing in The Pavements.
The first out of town choir then followed on with Barlow Singers on Vicar Lane and Rough Truffles from Belper singing acapella in the library.
The festival was formally opened by the mayor and mayoress, Cllr Donald Parsons and his wife Diane, who were entertained by a section of the Barlow Festival Choir.
The entertainment in Vicar Lane continued with a performance by the Lindrick Singers from Worksop and another out of town acapella quartet from Sheffield, Band Wagon, who sang in the Pavements with their barbershop harmonies.
The afternoon saw two new visitor choirs taking part with Kingston Community Choir from Barnsley providing sharp choral arrangements of many modern pop classics.
BVox, who draw members from South Yorkshire and Nottinghamshire, closed the proceedings with a mixed bag of pop classics and African chants sung by a seven-strong choir.
The festival is part of the Barlow Proms season which culminates on June 16 with a classic Last Night of the Proms concert on Barlow recreation ground.
