There were plenty of big, buzzy moments during Sunday’s Oscars. But it was a quiet, heartfelt tribute that became the top trending moment of the night.

Tim McGraw took the stage and sang a spare, emotional version of Glen Campbell’s Oscar-nominated song “I’m Not Gonna Miss You” – filling in for Campbell himself, who was unable to attend due to his deteriorating health.

Searches for “Glen Campbell” spiked some 211 times, more than any other name associated with the broadcast, according to Google.

The country legend, 78, was diagnosed with Alzheimer’s disease in 2011 and was moved into a memory care facility last year – though his wife, Kim Wooden, told PEOPLE this month that he is "healthy, content and jovial," although “cognitively, he’s declined quite a bit.”

Three Oscar winners – J.K. Simmons, Julianne Moore and Patricia Arquette, in that order – enjoyed the next-biggest spikes in Google searches during ABC’s telecast.

Google also shared data on the most-searched dresses and hairstyles from the night. Lupita Nyong’o led the former category, followed by Cate Blanchett, Jennifer Lopez, Dakota Johnson and Rosamund Pike.

Faith Hill had the most-searched hairstyle – which matched her husband McGraw’s! – followed by Scarlett Johansson, Johnson, Brad Pitt (who did not attend this year) and Melanie Griffith.
