A clash of egos led to Loggins and Messina splitting up in 1976. Loggins felt the need to prove he could make it on his own, saying on the website for their 2005 reunion tour that the relationship had become an unhealthy one for him because he viewed Messina as a mentor and eventually, he had to move on. He also points out that he had always intended to be a solo act. Loggins released his first solo album, Celebrate Me Home
, in 1977 and followed it up in 1978 with Nightwatch
, which features the hit duet with Stevie Nicks, "Whenever I Call You "Friend"
." His collaboration with Michael McDonald on "This Is It
" in 1979 led to his first Grammy. Loggins wrote the song for his father as inspiration to him when he was facing a life-threatening illness, transforming the original lyrics from a love song to a song about living.
