key and tempo of the song. Aware of the potential for incurring copyright legalities, the band debated whether or not to keep the line. Garbage and Brian Wilson coincidentally shared the same publishing company (Irving Music), and figuring that they had nothing to lose, contacted him through their company representative, sent him a copy of "Push It", and asked him for permission to use the interpolation. Wilson gave his blessing, and reportedly kept the tape. Both Wilson and Roger Christian, the deceased co-writer of "Don't Worry Baby", received a writing credit. A simpler interpolation credit was given to Herbie Azor, as the band's lawyers felt that there was a possible similarity of the line "Push it!" to his own "Push It", which had been a hit single for New York hip hop trio Salt-N-Pepa.
