"Like To Be You" features a guitar solo from Mendes' friend John Mayer, who also produced the track. Mendes first met Mayer in 2016 and the Canadian said his Illuminate
album, released the same year, was influenced by Mayer's work. The pair performed together the following year at the US musician's concert in Toronto, collaborating on a duet mash-up of Mendes' "Mercy
" and Mayer's "In Your Atmosphere." Since then, Mayer has become a mentor to Mendes.
