I was worried that it would rain, as the day was distinctly grey, damp and overcast (and jolly cold) but the sun came out just in time for the procession. Andrew Bosi, who used to run the schola which visited Blackfen for the Missa Cantata on the first Saturday of the month, came down to help with the singing of the psalms and antiphons during the procession. This was just as well, because I'm not yet confident enough to do the full Gregorian chant... we had the "proper" stuff for the procession and the Rossini propers (based on simple psalm tones) for the Mass itself. Together with Mass XVII, Credo I, the Stabat Mater and the Parce Domine, I think we did quite well...
I managed to get a few photos of the whole thing, and have uploaded them to my Flickr page. Please do go and have a look (and see what you are missing if you don't get to attend a Solemn High Mass for the start of Holy Week!
