He is arguably one of opera's greatest living singers, but Placido Domingo is making retirement plans.

The tenor is currently conducting Bryn Terfel and Sondra Radvanovsky in Tosca at London's Royal Opera House.
In his only TV interview during rehearsals, the 73-year-old admitted he would not be leaving the musical arena when his operatic career ends.
"One day logically I won't be able to sing," Domingo says, "and I will only conduct."
The Spanish singer made his Opera House debut in Tosca in 1971. He later conducted it there in 1996.
More famous for his singing, Domingo has conducted operas around the world, including Madame Butterfly in Vienna and Don Giovanni in Los Angeles.
But before he concentrates exclusively on this side of his career, there are plenty of starring roles to be undertaken.
Domingo will sing before a World Cup final for the sixth time on 11 July, and he will be returning to the Royal Opera House's stage next year for roles in I due Foscari and La Traviata.
