In the bridge, if you like you can do add a Db chord (1114) into the mix if you wish. It mimics wah-ooos the "ghouls" are doing in the background.
"Monster Mash" is a 1962 novelty song and the best-known song by Bobby "Boris" Pickett. The song was released as a single in August 1962 along with a full-length album called The Original Monster Mash, which contained several other monster-themed tunes. The "Monster Mash" single was #1 on the Billboard Hot 100 chart on October 20–27 of that year, just before Halloween. The song was re-released several times and appeared in the U.S. Billboard charts on two occasions after the original release: August 1970 and May 1973. The BBC had banned the record from airplay in 1962 on the grounds that the song was "too morbid". It was re-released in the United Kingdom in 1973, where it peaked at #3 in early October. In the U.S. the record re-entered the Hot 100 on May 5, 1973, peaking at #10 on August 11.It has been a perennial holiday favorite ever since.
