"Werewolves of London" is a song composed by LeRoy Marinell , Robert Wachtel , and Warren Zevon and performed by Zevon. Included on Zevon's album Excitable Boy, it featured accompaniment by bassist John McVie and drummer Mick Fleetwood of Fleetwood Mac. It was memorable for its humorous and macabre lyrics, and the refrain featuring a howling "a-hooo!!"

It reached number 21 on the Billboard Hot 100 in 1978, Warren Zevon's highest ranking single, and remained on the chart for 12 weeks. It was featured in the 1986 film The Color of Money.

In April 2004, a BBC listener poll selected the first verse as number one in a competition for The Greatest Opening Song Line. [1] That opening line is:

I saw a werewolf with a Chinese menu in his hand

Walking through the streets of Soho in the rain

He was looking for a place called Lee Ho Fook's

Going to get a big dish of beef chow mein
