In 1910 Drummond exhibited at Frank Rutter’s Allied Artists’ Association, and thus became absorbed into the gatherings and activities of the Fitzroy Street Group, which he recorded in an oil painting, 19 Fitzroy Street
c.1913–14 (Laing Art Gallery, Newcastle).1
He was an intelligent, sociable addition to the group and remained on particularly friendly terms with Sickert throughout his life. Like his former teacher he enjoyed intellectual debate and as well as being a prolific letter-writer, he contributed a regular column to the Scotsman
on a variety of subjects. He also built up close friendships with the Bevans, Spencer Gore and with Charles Ginner whose portrait he painted in 1911 (Southampton City Art Gallery).2
When the decision was taken to form the Camden Town Group in the same year, it was Ginner who proposed Drummond for membership.3
Drummond exhibited at all three Camden Town Group exhibitions in 1911–12. He also submitted work to the Salon des Indépendants, Paris, in 1913 and subsequently joined the London Group as a founder-member, exhibiting with them regularly in 1913–32, and holding the post of treasurer in 1921.
