Considering what we know about Johnny's skill in the studio-- his ability to play multiple instruments, willingness to experiment, the new ideas he brings to each project he works on, etc-- it's likely that even songs that don't list him as the songwriter feature a big contribution from him.
We all know that Johnny has a long history of playing with other musicians throughout the years - Liam Gallagher, Kula Shakar, Lisa Germano, Jane Birkin, Electrafixion, Beck, Bert Jansch, Haven, Charlatans, The Cribs. Any influence he's had on them and their songs aren't necessarily reflected in the writing credits. These are some songs
officially attributed to Johnny.
Walking Down Madison written for Kirsty MacColl
Concrete Sky co-written with Beth Orton
Even A Child co-written with Neil Finn, Johnny's daughter Sonny sings backup vocals along with other kids
Gravitate To Me co-written with Matt Johnson
The Boy Done Good co-written with Billy Bragg
We Were Dead Before The Ship Even Sank MM group credit
Here's what Johnny had to say about that collaboration, "Isaac contacted me and asked if I'd help Modest Mouse write the new album. I was intrigued and played with the band in Portland a couple of times. We hit it off and wrote three great songs straight away, something clicked, it felt right from the off."
Any honest discussion about Johnny's song writing
shouldn't dismiss his collaboration with Bernard Sumner with
Electronic,
Raise The Pressure and
Twisted Tenderness or Johnny Marr and The Healers
Boomslang.
