Summer (concerto)
From Tardis Wiki, the free Doctor Who reference
"Summer" was a piece of music, composed by Vivaldi, that was part of "The Four Seasons".
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)
