Such a tough call. All are equally favs of mine on this list, and more I can't think of atm.
Ds:
Sultans alchemy version
It never rains
On every street!! (ostatinato outro riff)
Tunnel of love
Telegraph road (happy and sad solos both)
MK solo:
You don't know you're born!! (Simple perfection)
Speedway to Nazareth (chills down spine good)
Darling pretty (perfection)
Piper (tears to eyes good)
More emotion in those solos for me than some entire genres of music.
