Vivaldi
From Tardis Wiki, the free Doctor Who reference
Vivaldi was the composer of "The Four Seasons", which included "Spring" and "Summer".
When the Sixth Doctor called Signpost to determine why it was interfering with his TARDIS, the "on-hold" music was "Spring". He listened to it twenty-one times and angrily demanded of Vishesh Abeyesekere that he play something else, even if it was only "Summer". (PROSE: Outsourcing)
