Walk On By.

Tonights song is 'Walk on By' performed by Isaac Hayes. This song was originally penned by Burt Bacharach and Hal David for Dionne Warwick in 1964. It became a big hit for her, reaching number six on the Billboard charts. Five years later is when Isaac Hayes would turn it into a twelve minute jam, though the single version reduced it down to under five minutes. It peaked at number thirty on the charts for Hayes. Since then there have been covers done in the style of punk, boogie, electronic, garage rock, and various other styles. Seal is the most recent example (2005) of someone who covered the song and saw it chart, though only in the low to mid range of various European Countries charts.
