First time I've read this.

Sorry I took so long.
I happen to have all of Sedaka's top 40 hits. On one LP I have the '50's to early '60s. The second LP is all of his 1970's hits (I also have an "el-cheap-o" CD with "some" of those same songs.
Finally,I have a 45rpm copy of his 1980 duet with then young daughter Dara called,"Should've Never Let You Go"
(Or was it Never Should've??... There's song by a '90s R&B group Hi-Five with a similar title,I get them mixed up sometimes). :D
