Crabbe was able to keep up his friendships with Burke, Reynolds, and others during the Duke's occasional visits to London. He visited the theatre, and was impressed with the actresses Sarah Siddons and Dorothea Jordan. Around this time it was decided that, as Chaplain to a noble family, Crabbe was in need of a college degree, and his name was entered on the boards of Trinity College, Cambridge, through the influence of Bishop Watson of Llandaff, so that Crabbe could obtain a degree without residence. This was in 1783, but almost immediately afterwards he received an LL.B. degree from the Archbishop of Canterbury. This degree allowed Crabbe to be given two small livings in Dorsetshire, Frome St Quintin and Evershot. This promotion does not seem to have interfered with Crabbe's residence at Belvoir or in London; it is likely that curates were placed in these situations.
