Pick your best songs. Sing what you know, sing it really well, and use the rest of your repertoire to fill out a live concert. Okay, okay, maybe I'm being a bit harsh. This was their 1st album and the rough edges can be expected to show. The pitch drifts in several songs which end slightly lower than they started.
Subtle accelerations seem to consistently creep into the faster-paced songs.
And the arrangements overall are nothing more than standard, or even too simplistic at times. As for The Beatles' Yesterday and Lionel Richie's Hello , I'm still wondering why they ended up on this album - not horrific, just grossly out of place. All in all, a good first try. If you're a doo-wop fan, maybe you'll borrow it from a friend before you decide to buy.
