Andrea Jenkyns, the MP for Morley and Outwood, joined Tuesday night's debate on the government's Fisheries Bill.
However, before she spoke about the proposed legislation, an emotional Ms Jenkyns told MPs: "If I may just take a few moments.
"I've just received a text message alerting me to the news that a good friend of mine - and former guitarist and former band member - has just died following a two-day battle with coronavirus.
"I just want to send my love and prayers to his wife and pay tribute to a gentle giant and an awesome guitarist, and a true family man.
"So rest in peace, Steve."
As she began her contribution to the debate on the Fisheries Bill, her voice broke with emotion.
Minutes before speaking in the Commons, she had posted on Twitter: "So sad, RIP to my friend, old band member and guitarist Steve who has died from COVID.
"A truly decent chap and family man, who will be missed immensely by his family and friends.
"God bless big guy and prayers for the family."
Earlier on Tuesday, Ms Jenkyns spoke in the Commons in support of the government's new three-tier system of localised COVID-19 restrictions.
She said: "As Conservatives, we suffer by instinct from the imposition of restrictions - I personally do - but we would not do it unless it was extremely necessary to safeguard lives."
