Last week I had to do a "tour" of suppliers in the midlands and Yorkshire , which I was looking forward to but not the travel or the hard sell I knew we would have so wasn't feeling Christmassy
I arrived at st pancras at 07.15 and as I collected the tickets from the machine I heard a vague brass sound. Went downstairs for a posh fair trade coffee and outside the coffee place I like was the Sally Army band playing carols . Instantly happy and all the shrapnel in my pocket went in the tin ( all I had after the coffee ! )
On Sunday I went to our old church ( left after a unwelcome at a carol service 10 yrs ago) for the carol service to earn brownie points with the MIL . They had a brass quintet playing to several carols, and the organ was fixed and sounded very good , to the point I might go back in January for regular Sunday communion
So yes brass works with carols
