"Stroll On", which had only been available on the Blow-Up soundtrack album, was included. It is one of the few recordings to feature both Beck and Page on dual lead guitars. "Think About It", B-side of the last Yardbirds' single, was released only months before Led Zeppelin was formed. Page later used the guitar solo from the song for his solo in "Dazed and Confused", one of Zeppelin's signature songs.
