Help me pick out music for a party

Wow..I'm 56 and don't consider it a party without dancing (but then my wife has been teaching ballroom and Latin dance for 25 years).

The few 50 parties I've been to that had music playing, that wasn't obtrusive, yet not invisible;

Steely Dan - anything
Spyra Gyra - anything

Well Thanks for everyone's help. Everyone had a great time and only one person had a comment on the music.

The Line up U2 Joshua Tree playing when guests arrived.
Van Morrison Live album from San Francisco (1 cd only)
Roger Eno - between tides
Tom Russell - Modern Art (3 songs)
John Coltrane and Johnny Hartman
Ricki Lee Jones - It's Like This
Bootleg of recent winwood clapton concer.

Thanks for all of you ideas. It was a terrific party and my wife had a great time until this morning.

Have fun and I learned a lot.

Towards the end, put on Van Morrison "Into the Music" It'll get 'em dancing every time.
