Encouraged by deWaverley's recording of Dyson's voluntary in D, I thought I'd offer this, it's from '5 Short Pieces' published in 1930. Percy Whitlock was a fairly prolific English composer of mainly liturgical music - he was organist of Rochester Cathedral - and this has always been a favourite of mine (even though I don't play it particularly well, and wish it wasn't in G flat!) I hope you like it.
