[8][9] When keyboardist Roger O'Donnell left the Cure in 1990, Bamonte was promoted to a full member of the band, playing both keyboards and guitar regularly, as well as six-string bass and percussion occasionally.

Due to the departure of guitarist Porl Thompson and the return of Roger O'Donnell during this period, Bamonte's duties for the band shifted to a stronger focus on guitar and less on keyboards.

[11][12] Despite the abrupt dismissal and the lack of an official statement describing the reason, Bamonte and Smith remained on amicable terms.

[15] In 2019, Bamonte joined fellow members of the Cure, past and present, for their induction into the Rock and Roll Hall of Fame.

[16] In a move that had not been previously announced, Bamonte rejoined the Cure in 2022 for the first performance of their extensive Lost World Tour, and has remained with the band since.
