For more on this, look in the 1980's section on the Meat Loaf wikipedia page below (where I found this):
"Early in the production of a follow-up album to Bat out of Hell, Meat Loaf developed vocal problems and was unable to continue on the project. Steinman proceeded with the album, released as Bad for Good in 1981. Most songs are sung by Steinman himself. Three of the songs are sung by Rory Dodd, who did not receive a clear indication for his work in the album's credits. Karla DeVito sings a duet part on one song. Steinman was this time credited as co-producer with Todd Rundgren for all but one track. Steinman was credited as co-producer with Jimmy Iovine for the song "Rock and Roll Dreams Come Through". The highest charting song from this album was "Rock and Roll Dreams Come Through" which reached #32 on the Billboard charts. In total the album has sold over one million copies."
