Yes, this serious-looking young man grew up to be legendary Led Zeppelin bassist John Paul Jones. Jones (born John Baldwin on Jan. 3, 1946) has gone on to build a successful and impressively eclectic recording, performance and production career since the breakup of his most famous band.

Although he's often overlooked in favor of more flashy bandmates like Jimmy Page and Robert Plant, without Jones' bass, keyboard, songwriting and arrangement skills, it's safe to say Led Zeppelin wouldn't have flown nearly as high. Our list of the Top 10 John Paul Jones Led Zeppelin Songs illustrates this point nicely. His post-Zep career highlights include four acclaimed solo albums, orchestration work on R.E.M.'s 1992 masterpiece 'Automatic for the People' and joining forces with Dave Grohl and Queens of the Stone Age frontman Josh Homme in Them Crooked Vultures.
