Each band member continued with his solo career over the next 20 years. Sting continued recording and touring as a solo performer to great success. Summers recorded a number of albums, both as a solo artist and in collaboration with other musicians. Copeland became a prolific producer of movie and television soundtracks, and he recorded and toured with two new bands, Animal Logic and Oysterhead. However, a few events did bring The Police back together, albeit briefly. Summers played guitar on Sting's album "...Nothing Like the Sun" (1987), a favour the singer returned by playing bass on Summers' album "Charming Snakes" (1989) and later singing lead vocals on "'Round Midnight" for Summers' tribute to Thelonious Monk "Green Chimneys" (1999). On 2 October 1991 (Sting's 40th birthday), Summers joined Sting on stage at the Hollywood Bowl during "The Soul Cages" Tour to perform "Walking on the Moon", "Every Breath You Take", and "Message in a Bottle". The performance was broadcast as a pay-per-view event.
