In the 1960s and 70s I was a Broadway cast album boy. I knew - and liked - a few Bacharach songs but it was Promises Promises that made him legit for me. So, I do like very much:
Promises Promises
Knowing When To Leave
I'll Never Fall in Love Again
Alfy
Message to Michael
Raindrops Keep Falling on my Head
Do You Know the Way to San Jose?
The Blob
Window Wishing
