Vivaldi
From Tardis Wiki, the free Doctor Who reference
Vivaldi was the composer of "The Four Seasons", which included "Spring" and "Summer".
He once offered to teach the Doctor how to play the violin. (AUDIO: The Paradox Planet)
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)
