Saturday's CBSO concert celebrated Simon Halsey's silver jubilee as director of the City of Birmingham Symphony Chorus.
It's a quarter-century during which he has developed the choir to the status of being among the most sought-after choruses in the world.
During that time he has presided over an ever-growing family of offspring from the parent body.
What a pity he couldn't have chosen works other than the Holst and Vaughan Williams which he selected for this special event.
Both lean heavily upon outside influences (Wagner and Elgar between them), and their texts crumble under scrutiny. But Halsey loves them, and that's all that matters on such an occasion.
Holst's chamber-opera Savitri is a tedious tale of wifely love reclaiming her dead husband, and the composer's own text is a burden the music can scarcely carry, and which cannot help by evoking Wagner at key passages.
Yet this is scored for minimal chamber forces, busy and committed here, a disembodied female chorus (the splendid CBS Youth Chorus) and three soloists.
James Rutherford was commanding and compassionate as Death and James Oxley an eloquent woodman.
Sarah Connolly was rich and expressive as his grieving wife Savitri.
Rutherford was joined by Janice Watson in a committed solo partnership for Vaughan Williams' Sea Symphony, the CBS Chorus once again amazingly forward in its projection, even if some of the text remained unclear.
Not that that mattered.
Walt Whitman's over-rated, fustian verse demands more in its setting than it deserves to receive, and, unfortunately, Vaughan Williams relied upon Elgarian imagery to convey its pantheistic message.
The result is a compositional mess, and this performance required more magic even to get near making the music work.
