867-5309 (Jenny) for me. It was so successful that it thwarted the success of the band. They had a ton of good songs, but no other ones that had the thing that 867-5309 (Jenny) had. Tommy Heath and Jim Keller are smart guys who wrote the best dumb guy songs. Get Around Girl, Which Man Are You?, Dumb But Pretty, Laverne, National Emotion, Money Talks, I Wanna Touch Her, all fine songs.
The Breakup Song I haven't completely made my mind up about, other than it doesn't beat the above song.
Long Cool Woman has always seemed too close to being a novelty song, to me. It hasn't worn well in my listening and I generally change the station when it shows up on the radio.
