Query: Best left in the 70's

Insipid songs, lame production, cheesy arrangements, laughable singing. It all adds up to excruciatingly bad music from one of popular music's silliest eras. It is quite telling that David Cassidy HATED singing this stuff, and it is amazing that anyone who has managed to successfully complete childhood would have any interest in hearing this sap again.
