I have a Sinatra album on vinyl that I bust out every now and then when I am in the mood
Nice one man, music is magic like that, how you can almost forget about an artist and then something pops into your mind and you think ahhhhhh, let me grab an album and you are transported to another place.
I am guessing that is Irving Berlin and Cole Porter on two of them.
You know your music!! You're right, Cole Porter wrote "I Concentrate on You" and Irving Berlin wrote another song from the album "Change Partners"
